The codebases that you can create nowadays are light years away from what you would see 10 years ago. And the frameworks have improved alongside too.
I imagine it might crop up for people that also use Perl, since that would be more common there, like:
$foo="abc${var}def";
Kinda odd that Bash has had this syntax since forever, Perl as well, JavaScript went out of its way to add it as well, and now php is like: let's remove this syntax specifically but allow typo variants of it!
Oh well. Not like I was using it, that is, I use the bare "$foo" syntax and try not to make string interpolation too complicated with inline expressions or some such. Just, I could have seen the logic behind switching to the more universally supported syntax and deprecating something else rather than doing their one-off thing.
PHP supported versions - https://www.php.net/supported-versions.php
I'll also point out that in shell assignment looks like
a="foo"
$a="foo"
`words ${var} more words`
I thought we would start seeing more usage of this in PHP to make things more consistent.
The language isn’t perfect but I love working with it, these 8.1 and 8.2 improvements have really made it sweet.
My biggest gripe at the moment is the (very old) behavior of e.g. preg_match() and sort(). You’ve got a small handful of these common functions that operate on their input by reference/in place which is gross. A new version of these would be welcome.
Maybe read https://stitcher.io posts about the new features since 8.0 to have a grasp of the language changes.
Note: I think PHP is way under appreciated.
Python 2 -> 3 change really was painful for Python community, but PHP does these almost fundamental breaking changes so often, that maybe people just get used to it? I haven't really followed Python past version 2, but I think they are less likely to ever do such amount of breaking changes.
There must be a lot of unmaintained PHP codebases that will break if PHP is updated by hosting provider etc. Someone must be pulling a lot of hairs because of this.
Edit: Those dogpiling there, I rest my case with josefresco's comment:
https://news.ycombinator.com/item?id=33907628
It's painful. Dropping dynamic properties? That will be a lot of fun. WordPress is probably biggest segment for PHP usage.
PHP 7 made a few big and necessary changes but they generally did not affect well-written code much. Python 3 broke a lot of things without good justifications, and without a way to make your code compatible with Python 2 at the same time.
Edit: I'm talking about the php code being compiled / run by an external process which makes the whole thing staless.
It was a "working" design when people were dropping .php files in ftp folder on some hosting provider.
Major update, awesome. /s
As someone who manages a network of 250+ WordPress websites - these PHP updates are killing me! As soon as I'm done helping clients upgrade/fix their incompatible themes/plugins and custom code, a new version is out! Even with great tools, the process for about 10% of my network is a nightmare.
While I appreciate the work, it's not very satisfying and for many clients very frustrating to pay for something they know nothing about, just to "keep the lights on".
PHP has gone through a few changes.
PHP 3->4 was a moderately big change under the hood, and introduced a lot of new things, but most 3 'worked' under 4 (but was... awkward).
PHP 4->5 - a few 'big' things changed - XML processing changed - I had to use some shims to get some projects upgraded.
PHP 5->7 - my recollection, and that of most colleagues, is that this was pretty painless for most projects. I can't recall too many major breaking changes, but it was mostly just getting a doubling of speed without any substantive changes.
The PHP community has a couple decades of 'major version changes' to look at to learn from. I still can't say I agree with 100% of the decisions, but it's still progressing nicely.
> There must be a lot of unmaintained PHP codebases that will break if PHP is updated by hosting provider etc.

Also not a PHP problem but a WordPress problem. It's not a healthy eco-system.
That said there are languages where very little backward incompatible changes are made. Java comes to mind.
Also: putting each client in a sandbox (VM, VPS, etc) can help you to keep some clients on the old versions, and/or do PHP interpreter migrations on your own timeline.
I'd argue that's true for all of PHP. Sure it got better, but compared to other langugaes it is still a mess.
How do you deal with Nginx/Apache updates given they release more frequently than PHP?
You can always host at a managed hosting provider who will take care of this for you.
The plugin/theme developers usually develop with older versions of PHP in mind, lot's of plugins still work even with 5.x versions...
For my WP sites I just stick with "two major versions behind" workflow and I don't encounter many problems.
Am I doing it wrong?
Great! Keep using it! Ignore us. We (detractors) also had to use it and have since learned (hopefully several) other languages that (not looking at you JS) we like much better... :)
PHP didn't learn from Python 3 BC fiasco, its governance makes such changes very difficult to be made.
I even host a few installs on the latest 7.x version.
I don't understand where this update hysteria comes from. PHP 8.1 security support ends in Nov 2024.
Even as someone who supported it. Perhaps there was internal built up resentment.
Whatever it was it showed in their communication.
Very occasionally I have to communicate on a topic I think could see backlash based on internal views. I make an effort to communicate it as neurally as possible.
My org currently prefers a saccharin approach when there is controversy I can't stand that, but I prefer it to over the like it or lump it bristling with rage approach Python took.
I hope you can give some factual arguments why it's still a mess.
If it's recognition for learning <insert-language>, how do I provide it to you?
If you've long moved on and are no longer using PHP, why do you still consider yourself a "detractor"?
7.4 just ended its security support so you might argue that you should be at least on 8.0 just in case a bug is found and not backported.
Truth is: it's not likely.
But in any case theres no need whatsoever to use the latest version and even less when you are using WordPress which is notoriously bad at keeping up with PHP releases.
The thing is that PHP is (was) a good example of bad language design. It's original creator is (was) also known for its total disdain for "correct working software". The language and standard library even more show this quite clearly.
See reddit.com/r/lolphp for a community dedicated to bringing PHP's bad design pearls to the surface.
PHP also cares a great deal about backwards compatibility. There are long deprecation phases before anything gets removed.
The RFC system also helps a lot in ensuring that changes to the language are well thought out to and discussed beforehand. The is not much change just for change's sake. Churn is kept to a minimal while still allowing the language to evolve.
> There must be a lot of unmaintained PHP codebases that will break if PHP is updated by hosting provider etc. Someone must be pulling a lot of hairs because of this.
PHP upgrades are also good money for agencies. Got to earn that bread.
And to let out a dirty secret, for really hopeless projects there is the option to keep them on life-support by running them inside a docker container with an older PHP version. (Horrible but if that's what the customer wants, it's their risk.)
2. Officially supported runtime that exposes system event loop to userland (yes, we have swoole and roadrunner)
You _can_ use PHP from the command line but it's not the same kind of thing as Python or other languages where you need to be mindful of which version some shell script might assume is installed, etc..
As per how to select versions easily, the Symfony project provides a Symfony CLI and one of the features it provides is checking for a `.php-version` file in the current directory and selecting the correct php binary from the PATH accordingly.
I use that when I'm dealing with projects on different versions.
>sleep(int $seconds)
>returns zero on success.
>If the call was interrupted by a signal, sleep() returns a non-zero value. On Windows, this value will always be 192. On other platforms, the return value will be the number of seconds left to sleep.
I've used it for 2 years 2 years ago and I'm not at all interested in starting a project with it again
EDIT: have you looked at ngx-php. It’s blazing fast and provides you that event loop.
I still occasionally work with PHP for WordPress and it is still mostly not great. The mess of abstractions, the JS-like library installation system, the lack of any kind of concurrency, the mess with errors vs exceptions.
It just isn’t a language that makes me happy. Then again, I dread opening a .php file so maybe it’s a preconceived notion.
They'd gather back my respect when they get rid of all the moronic behavior they have in the functions of their global namespace
* Like sleep that returns 192 on windows but not on linux when you interrupt it
* hash_hmac that if you pass array to $data, php will generate a Warning, return a NULL and continue, I'll let you imagine how bad this is in the context of hmacs when null gets typecast to 0 later on
* etc
PHP just happens to be good at getting stuff done fast, so it's found all over the place, and thus has a lot of eyeballs on it. The negativity is a byproduct of it's usefulness and staying power - the price of popularity, if you will.
I love PHP, especially with the new event loop based modules that let you do things asynchronously, much like Node or Go.
If you know how to use it well, PHP is awesome, and it's getting better with each release.
So there's some argument to be made to be in the 8.x series. It's probably not something you should be losing sleep over just yet, but at least have it on your roadmap to address in the coming months.
That's something up for debate. Personally, I'd like the shared-nothing approach but I'd like to have async capabilities to optimize I/O and a function that flushes the request and frees up resources for next request in queue.
edit: I haven't seen ngx_php, thanks for the link!
Eventually you have to upgrade. Do you want to go from 5.6 to 8.2 and possibly have to start over? Or do you want to go version by version, paying smaller amounts more frequently to stay current?
Also: WordPress + Themes + Plugins works best when you don't delay maintenance/upgrades. Everything needs to work in concert. You might be able to freeze your theme in time, but your plugins and the WP core will march on.
PHP 8 is in "beta support" currently, but that's just Core. A lot of plugin developers are lightyears behind it seems:
https://make.wordpress.org/core/handbook/references/php-comp...
PHP opened the door to cheap web dynamic web hosting and in turn you had self-hosted applications like Wordpress. It was a few years later that languages like Java and C# became really attractive for back end work, you also had Ruby, Node, etc.
I wrote a lot of PHP in the early 2000s because that is were the work was, that’s what you could write open source code that people would use in, and it was really straightforward to build apps (like a social network for a secret society) without an ‘ops’ team watching your every move.
Yes it's a userland workaround and not a fix for the language, but it's thinking about these issues and a PHP extension (offering better performance) is being talked about.
I don't. We just finished upgrades from 7.4 to 8.0. PHP 8 was release November 26, 2020 - two years ago!
> How do you deal with Nginx/Apache updates given they release more frequently than PHP?
My managed host deals with that.
> You can always host at a managed hosting provider who will take care of this for you.
I have a "managed" host and none of them will make your code compatible. It requires a software engineer and lots of unglamorous work.
I do and appreciate the job security but I respect my clients (small biz owners) and it's just not satisfying and for the 10% that have issues, costly.
Ding ding ding! This guys WordPresses. Even outside my network which is in decent shape, I have clients scrambling because they've ignored PHP updates for 2+ years. Sometimes burying your head in the sand is not the best strategy.
Shared webhosters (speaking for Germany) have started to disable support for PHP 7.x as there are no security patches anymore.
That made it necessary to upgrade lots of WordPress pages, especially older ones had some quirks in themes that broke with PHP 8.
I've updated around 25 sites for an old friend (she's more into the design/content part, not the dev part) and made good money with that. "Stupid" work nevertheless, would've preferred to do something better than run a PHP 8 linter and see where it breaks...
PHP is nothing if not amazingly well documented. This is more than I can say for a lot of languages I have worked in cough Ruby cough. I work pretty heavily in Go these days and even it’s docs leave me wanting in comparison sometimes.
Exactly. It's work for our engineers but not something to get excited about. Plus you need to explain to the client why they're paying $1000 for something called "PHP" which they have no concept of.
I know this is contradictory to what some people love about PHP, but having a directory where everything is isolated and I just run npm start or my go binary or whatever is much easier to reason about for me, rather than also have to think about Apache's end.
Do you mean how you can have an optional out parameter to get more detail than what the return parameter gives for which group matched?
Personally i dont see anything wrong with that, but to each their own.
That being said, one issue I've found is that while I can use VSCode for every other language, using PHP feels terrible if I'm not using a JetBrains IDE. I tried installing the PHP extension pack, but it was still leagues behind. Is there any guide someone can recommend for making PHP a first-class language in VSCode, or am I stuck in phpStorm?
WP Core is absolutely compatible. Its the themes, plugins and custom code (usually in functions.php) that isn't.
We upgrade our clients in waves, so sites in dev get the latest PHP, which lets up contribute to upstream PHP projects to fix issues, and by the time it's merged upstream, we can update our older clients without any worries.
Java used to be like that, but the migration to the module system has been very rocky for me personally when revisiting older projects.
It's unreasonable to expect standard hosting providers to cater to those kinds of needs IMO.
Totally not, yeah!
My friend also was surprised/shocked that there were changes in the code necessary to keep those old sites up and running.
Next thing was installing and setting up the "OMGF" plugin to cache Google fonts for GDPR compliance. Stupid work, but quite a few billable hours.
I think the WordPress ecosystem really is... "struggling" (lack of a better word) with how the modern web and the world around it evolves.
Can't speak for Nginx, but Apache updates very rarely screw with syntax, and those are always major releases. And for Apache, "syntax" just means config files.
PHP screws with syntax frequently, and often on point releases. And PHP is a programming language; syntax is the whole point of PHP.
Libraries are infinitely preferable to frameworks if you want your application's life cycle to be independent of $POPULAR_FRAMEWORK's.
Even with Laravel, which is the current thing in the PHP world, I've worked in multiple teams where their application is written in a very old version of Laravel and there's no desire to attempt an upgrade to the most recent version.
* function autoloading
* typedef
* templating hooks for escaping output and such
* better phpdoc, e.g define class without creating class, nested structures.
* inner class
* modules (instead of namespaces)Wordpress has a lot to answer for here, but given the archaic and frankly idiotic way they operate they'll do nothing of the sort.
PHP is very backwards friendly and with a strong and stable ecosystem built around composer theres no excuses for majorly used (and often very profitable) wordpress plugins lagging so far behind.
It's just like the Rust folks never miss any chance to bash C++, while C++'s market share keeps rising and after 16 years since Rust was created, it can not even make 1% of the market while C++ is 12%(excluding C which is 16%,again it keeps rising).
Rust's goal by the way should just replace Ada for specific areas, to take on C++ on a broader level it probably needs another few decades, if it can ever make it that is.
This.
The PHP developers are trying to turn PHP into a decent, fairly modern language. This has involved quite a lot of breaking changes in the last few years, and upgrading website code just so it works with the latest version (i.e. no actual improvements) isn't appealing work.
Well that's the thing: I don't know anyone who actively develops in Ruby, Python, Perl or Node that uses the OS-packaged runtimes. The system packages and the language-specific package managers live in different universes.
I've seen this situation blamed on both OS packagers or language ecosystems, but now I just think the goals between the two just are fundamentally at odds.
It's also not a contest? I'm not sure why people care about these numbers. PHP keeps getting bashed because it's a bad programming language full of footguns, then and now, regardless of whether or not other programming languages exist.
The no-brainers to me are the missing array_some()/array_any() array_every()/array_all() and an array_search() that takes a predicate and iterable. I do these now in userland but an optimized native version would be nice.
I have a private (non-internet) web-app that's still on PHP6.5; I like the new PHP features, but upgrading private code to conform to PHP 7 and 8 looks a lot like make-work. I wish it shipped with good upgrade tools.
[Edit] @darkwater (below) is correct; I meant PHP 5.6. PHP6 was some kind of abortion - I can't remember the story.
It's possible that PHP's ubiquity and the core language's poor architecture/design (for decades now) are the source, not the ignorance of those complaining. PHP was the very first programming language I learned, in 1997. If anything, I mostly stopped disparaging it because I simply moved on in my career enough to be able to choose languages that aren't constantly fighting me.
I'm a consultant so I get asked about unfucking PHP codebases every few years, and I check in on the ecosystem and language. It's better but (unsurprisingly) still not great. Meanwhile, languages a decade+ younger avoided PHP's mistakes.
There's resources like laracasts which take you through from the basics to highly complex concepts without it feeling like you're being lectured.
One benefit of Laravel is that under the hood it shares a lot of Symfonys core components so should you decide to switch at some point it's not too much of a learning curve.
A lot of cPanel or similar hosts are also retiring old versions as they hit EOL [1][2][3][4][5] (those all support 7.4 still but most have indicated that will be dropped next year as well). This has made hosting transfers more and more difficult if you don't want to go through the process of upgrading.
The process of upgrading Wordpress sites isn't so bad (generally there's no work, honestly). But not all CMSs are that simple and it can get more laborious when you want to upgrade a Laravel or Symfony site, especially if you've skipped a few versions.
Of course, at the end of the day, it's up to the client to provide budget for these things and if they don't/can't, you just have to push back on their other requests until they do.

They replaced the MySQL plugin in version 7. All MySQL code was broken. I don't know, but I'd guess that most PHP sites were using MySQL as their database (the 'M' in 'LAMP' stands for MySQL).
For better or worse, there's some degree of 'upkeep' that has to be done with any code, if only to take advantage of some newer tooling (even ignoring security and performance concerns).
> and there's no desire to attempt an upgrade to the most recent version
That seems to be a problem there. I would not want to be using, say, Laravel 4 in 2022. Nor early Symfony, or any other framework (or library) that is years out of date.
What's been interesting to watch in Symfony and Laravel is to see an ecosystem grow around them which amplifies the value of using that framework (laravel shift springs to mind, based on your example above).
The danger seems to be in being complacent, regardless of tool choice. I've had to go back to Java/Spring code I wrote 10 years ago, and it's... challenging to make some things run again.
If it's all your language does, I do not think it counts as a benefit. Not in my book at least.
That won't really solve having config files at different places though.
The projects I start today got the php replaced by typescript
I hate language-specific package managers. I can see their value to packagers (less work), but they end up arguing with the platform package manager.
It's like there's a load of CS graduates churning out lots of new, better languages; but what's really needed is just one better language. Similarly we have a score of new package managers, creating incompatibilities; so we add some more package managers, to paper over the incompatibilities.
I'm inclined to the view that perhaps there are too many coders in the world, creating compilers and package managers because they can't get a job doing something useful.
https://www.reddit.com/r/linux/comments/nnxng/petition_lenna...
But I get your point. :-)
Moving from 7.4 -> 8.2 will be just as much refactoring as moving from 7.4->8.0->8.1->8.2. Security support is in general three years [0] so everything 7.X is now unsupported. Considering the security cadence you can skip one version, but if you skip two you'll probably be out of security support before you migrate to a new version. My philosophy is if you're going to need to do the work to upgrade anyway, you might as well do smaller chunks more frequently and be able to take advantage of the language goodies that come out earlier.
The amount of the language that gets deprecated every year is PHP's fundamental flaw, at least in the last five years.
Like the poster above: I totally support PHP ... it is good, it has surprisingly well aged in the recent years, and it perfectly has its place ... but it has warts. Nothing bad, nothing tooling could not compensate ... but there are warts because of its origin.
Other languages has warts too: Java has no real generics, Python has it when you do indenting wrong and let us not start on JavaScript or god forbid VisualBasic. As a C# fanboy, i have to rely on others to see warts there ;)
Non-java devs think of java as Java 6 when in reality it has pretty significantly evolved in the last decade. I dare say that it's one of the most rapidly evolving mainstream languages on the market at this point.
Then I read a little closer, and realized I pretty much just had to add an "i" onto all the underlying mysql functions ("mysql_" to "mysqli_"), at least for the ones I was using commonly.
I'm still in the process of migrating that project, now on 7.4, to a modern Symfony framework, but I tested it out in 8.1 the other day, and it needed...1 change to work apparently perfectly.
I'm still going to need to do more thorough testing before I put production on 8.x, but with 7.x now unsupported, that has become a priority.
A hosting provider that forces people to PHP 8 is not a good hosting platform for WordPress.
Php is in a very similar situation, the difference is you can't escape javascript so we all to some extent keep up with its developments. People who leave php left it at a certain point and their understanding of its issues is frozen there. It's very predictable and boring honestly.
It has some nice things but for everything in PHP, there other languages that do it a lot better. And I don't think CGI is a killer feature in 2022, it doesn't matter anymore than any other implementation detail, and causes more problems than it solves.
What "external" process are you talking about?
1. Compile PHP yourself (no)
2. Use an untrusted third party repo (probably not)
3. Upgrade OS to latest
4. (apparently) Use FreeBSD instead.
For all I know this could change. The current release schedule of PHP is greatly accelerated from what it was 5-10 years ago, and we're all still adjusting I think.
Edit for context: the small business that I work for takes on all kinds of random web work. It's not uncommon at all for us to be asked to rescue an application or website that's still running on PHP 5. For projects that we have initiated, by the time we migrate them all to PHP 8.2, it will be End of Life.
What does that lib do that PHP doesn't?
I've used it to build ~5 websites and it's been very solid. The docs are pretty good and it does most of what you need out of the box. Especially the 8+ versions of Laravel. If there's something you need that's not included in the framework itself, it's likely there's a well-maintained community package.
Just my 2c.
Does it deterministically pass ALL tests in its own test suite yet? 100% of the time? This was the state just a few years ago, where a lot of tests were simply disabled because they were "flagging". <insert eyeroll emoji> (I'm not even going to touch the Boolean chart showing the different behaviors of single, double, and triple-equals on results. I know a lot of that has been fixed, at least by "convention".)
Nondeterminism is literally the worst trait of a computer language, because it leads to the worst kinds of bugs- the ones that are NOT a result of your lack of understanding of how the code is supposed to work at the PHP level. I've literally burned months away in my career in tracking down bugs like this (in Ruby and other languages), which ended up being framework or language bugs. There comes a point when you say "never again". Unfortunately, it comes too late in most people's careers to realize they've made a mistake, and switching to another language/community becomes too expensive/risky a proposition for them. (In my case I've been fortunate in that I was able to switch from .NET, to Ruby, to Elixir... each one of these was a difficult transition, both intellectually and socially (I really miss the Ruby community!), but in the end, completely justified in my case.)
I've only done PHP for small personal projects and some wordpress hacking, and that was years - so my experience is limited. But it seems to me that one of the great and tragic things to PHP is the low barrier to entry. As you put it: "first open source language in which just anybody could write server-side web applications without terrible management problems for the sysadmin".
This made it extremely easy for anyone in the early 2000s who signed up for a web hosting account on godaddy/hostmonster/hostgater/etc... to fire up a text editor of their choice and start slinging code and FTP'ing up to a server. Didn't have to worry about installing, configuring, all the dependencies, build tools, etc... just edit, upload, refresh -- lather, rinse, repeat until it works. Lowered the barrier to entry, and got a lot of people into the field. Really powerful stuff.
It also made sloppy, hacked-together, copy-pasta code very prevalent. In my limited perspective, I suspect that this prevalence of sloppy spaghetti-code has contributed to PHP's bad reputation. It's not that you can't do good code (totally can!), but a PHP environment can be forgiving of some pretty bad practices.
But you can use strict_types! With strict types, PHP 8+ is a very nice language.
I don't like arguments like these because they're a tu quoque without even bothering to point out flaws in a different thing. It implicitly states that progress is impossible, that all languages will always be as bad, and nothing can ever improve because once a technology is widely-used, design flaws will magically appear. If you really believe that, write your next website backend in FORTRAN IV.
It was lazy argumentation when it was people saying Linux was just as buggy as Windows Me and it's lazy argumentation now.
This model is imo outdated, why can't we create a PHP server that just runs without the need of something external.
PHP has a low barrier to entry, but that's a great thing in my opinion. It's something that should be celebrated, and at the very least, it shouldn't be a criticism!
Bad developers exist in every language, and no language is completely wart-free. People just like to zero in on PHP to criticise it because it's easy, and it bugs me a bit (especially if they're simultaneously singing the praises of another less than perfect language such as JS or Python or Go).
At that time you could have made similar software for JSP, ColdFusion or ASP.NET but hosting would have been much more expensive and a big hassle. With PHP it was feasible to offer a $5 a month hosting plan good enough for blogs and simple web application.
I wrote a lot of PHP because it was a great way to deliver products to customers, particularly ones that didn't have a lot of resources for "ops" but also a place where I could write open source software which might really get used and have an impact.
I don't recall the sequence of events that way. That is, there was regular cgi, then mod_php with problems similar to mod_perl...then later fastcgi options existed for both.
GP's problem seems to be that they have to support WordPress plugins and themes that they either can't or don't want to patch by themselves. This is a different situation from people who build & maintain in-house apps. In that case, always using the previous Ubuntu LTS is a perfectly viable solution. Stay 2-3 years behind the edge, giving enough time for the plugins and themes to get updated, while still receiving security patches and comfortably within the recommended range for WordPress Core.
Also, I'll not pick any of the interpreted languages for that matter and would want Golang/Crystal/Nim to get single binary to be packaged.
But of course - this isn't necessarily something everyone would do.
There are no right or wrong answers here I suppose.
What's the newer fastcgi php method that isn't mod_php?
FastCGI is a protocol that allows a web server to communicate with external programs that provide dynamic content, such as PHP scripts. In FastCGI, the web server launches an external program, called a FastCGI process manager, which is responsible for starting and managing a pool of long-running PHP processes. When a request for a PHP script comes in, the FastCGI process manager assigns one of these processes to handle the request, and the process generates the dynamic content and sends it back to the web server.
mod_php, on the other hand, is an Apache module that embeds the PHP interpreter directly into the Apache web server. This means that PHP scripts are executed directly within the Apache process, without the need for an external process manager.
While both FastCGI and mod_php are ways of running PHP on a web server, they differ in their implementation and how they handle requests for PHP scripts.
That said, I'm still surprised when I come in to codebases where people are still using hard-coded db function calls all over the place (mysql_* or mysqli_) I indicate that abstracting that away should be a priority. Even doing something as simple as "I want to log all the queries that I'm making for debug purposes" is essentially impossible when you have hundreds of individual calls to mysql_ embedded throughout the code. But... I've not come in to a codebase in the last... 4-5 years that does that, so either I've been lucky or that coding behavior is indeed becoming a thing of the past.
https://www.php.net/supported-versions.php
I know the web needs constant maintenance, but I wish it wasn't so much. PHP has been pretty good about not breaking changes, but I've noticed a few..
PHP is my goto. Its pretty great. It enabled a startup I was part of to get off the ground.
Web or something else?
I ask because I haven't heard many using Crystal/Nim for web.
PHP-FPM is the server you're talking about. It's a supervisor process that forks into N child processes, each handling incoming request. Supervisor deals with child exits and respawns, keeping the whole thing alive and robust.
This model is what PM2 does for node.js to keep it alive when it crashes.
There's also PHP command line interface that lets you run a server by starting a PHP script, in which you get to access OS's event loop and various other lower level interfaces.
You don't seem to be knowledgeable about the topic and you're assuming something entirely wrong. Why didn't you google before this discussion?
One can start a synchronous, process-based server or event-loop async one. What exactly is outdated here and how does ANY other language do it differently?
The Java 8->11 transition was rough but honestly after that we've not really experienced a whole lot of pain. 16 has been a little bit of a pain as well since it closed some more unsafe holes. I think that's the last release, however, that's going to cause major headaches with migrations.
there is symphony/laravel as web frameworks, which by all accounts are modern and highly usable, but that in itself doesn't distinguish php given how many alternatives exist
As for the second part, I understand why system calls are interruptible, particularly before the implementation of many syscall-level asynchronous operations. However, too many languages require too much boilerplate in the much, much more common case where the developer wants the appearance of an uninterruptable system call in a multi-threaded and/or multi-actor program.
I've written plenty of interruption-safe sleep and I/O code in C. It's disappointing that same C boilerplate needs to be used in PHP, Java, etc. If you want to expose the interruptiblity of a C sleep(), call it interruptible_sleep(), and make sleep() a wrapper that contains the boilerplate you want 99% of the time in C. I dare say 90+% of programmers don't properly deal with interrupted sleep system calls, and exposing the interruptions should be opt-in.
In retrospect, at the syscall level, the C library interface to interruptible syscalls should take a function pointer to an interruption handler that returns a boolean as to whether the syscall should be transparently resumed. Passing a null handler should result in the syscall appearing uninterruptable to the calling code. Most programmers are blissfully ignorant of interrupted syscalls and are perplexed by seemingly random resultant bugs. The default interface to these calls should protect the programmer.
// sleep(int sec) should look more like:
void sleep(int sec) {
sleep_interruptible(null, sec);
}
void sleep_interruptible(bool (*handler)(int), int sec) {
struct timespec ts = {sec, 0};
int prev_errno = errno;
errno = EOK;
while (nanosleep(&ts, &ts) != 0 && errno == EINTR) {
if (handler != null && ! handler(errno))
break;
}
errno = prev_errno;
}But PHP 7.4 is not compatible in many ways with PHP 7.3, so lumping them together is not OK. As you can see, PHP 8.0 which was only released two years ago, is no longer receiving active support. Definitely, database LTS is not comparable to programming languages. However such rapid releases of breaking versions is a relatively new phenomenon (thanks NodeJS), and I get the feeling that you've never actually supported a software project for 5+ years.
We’re always looking btw.
Deploying to the cgi-bin directory was more convoluted and error prone for end users. Even when you did it right all of your URLs had an "ugly" cgi-bin component.
The easy deployment and cheap shared hosting with their managed MySQL instances really helped boost PHP's usage.
Have you consider that people who learn other programming languages are not doing so in order to claim that they're better than PHP programmers, but for their own intrinsic reasons?
It's such a weird, fragile ego situation. Does everyone else have to pretend that PHP is the only language that exists in order to placate your sense of inferiority?
I'm speculating though.
The major niche has been carved long ago. Low cost code for budget conscience clients. PHP has long been the easiest on-ramp to webdev for many folks and some of the things out of it Wordpress specifically, can be utilized to cover a vast number of rather low complexity needs. If you consult with budget conscience clients, you likely find PHP indispensable. If you (or your employer) are building your own software product, you care more about DX and such and have chosen something else. In both scenarios, the end users of the product do not give a damn what it was built with.
Increased strictness in the types that can be passed to the built-in functions has been a general area of focus for the last several versions.
I get where you're coming from, I think the way I'd think about it would be a little different. The interruptible part is semi-specific to sleep. I'd want predicable naming for syscalls first and foremost. So something like libc_sleep(). (libc_open(), etc would follow too) This makes is more obvious you're dealing with a pretty raw api. But otherwise agree. I haven't written any PHP in nearly 20 years, so I completely forget: is sleep() pretty typical of how PHP treats these syscalls?
Not quite. Code that *wasn't* using either of the two modern APIs for MySQL was "broken".
They removed the oldest, jankiest of the three APIs for connecting to MySQL in php7.
MySQLi (literally, "MySQL Improved" extension) was introduced with PHP 5.0, in 2004.
PDO was introduced with PHP 5.1 in 2005.
The documentation started showing "soft deprecation" notices on mysql_* functions in 2012. It was already common practice to advise people to upgrade to either mysqli or PDO.
The old mysql extension was deprecated as of php5.5, in 2013.
The final shipped version with the mysql extension was 5.6, which was supported until 2018 - half a decade after the deprecation was added.
> Progress is impossible
Huh? My very last sentence implies quite the opposite.
Java has been slowly adding the best kotlin features (such as data classes, records) which also makes it a bit harder to sell.
That said, I've introduced kotlin on a few teams and pretty much everyone that's worked with it has complimented it.
If you can't trust Ondřej Surý's repo, you're gonna be disappointed when you see who maintains the PHP packages in Debian's official repo.
Isn't it better to tie projects to specific libraries rather than frameworks because it should be easier to swap/replace a library than the whole framework ?
(Or is that OOP kool-aid I still taste ?)
> Write an explanation for the user who posted the following comment: "Wait. Isn't fastcgi essentially the same as mod_php? IPC with a long-running process rather than forking and capturing stdout? What's the newer fastcgi php method that isn't mod_php?"
is:
> FastCGI and mod_php are similar in that they both use a long-running process to handle PHP requests, rather than creating a new process for each request. However, they differ in how they are implemented and how they interact with the web server.
FastCGI is a protocol that allows a web server to communicate with external programs, such as PHP, to handle dynamic content. It is typically used with web servers such as Apache or Nginx. In the case of PHP, the web server uses FastCGI to send PHP requests to a PHP-FPM (FastCGI Process Manager) process, which then executes the PHP code and returns the result to the web server. This allows the web server to handle multiple PHP requests simultaneously, improving performance.
On the other hand, mod_php is an Apache module that embeds the PHP interpreter directly into the Apache web server. This means that Apache can handle PHP requests itself, without the need for external programs or FastCGI.
how is it 16 years when Rust 1.0 was released in 2015?
Whether or not you should be doing that is another matter… but it’s useful in some cases and easier to grok than using reflection or using array syntax on an object (like JavaScript).
After awhile, you don’t even notice the $ to be honest.
All servers, of any kind, work the same way. Whether you want to accept it or not is not up to me, but fact remains.
PHP does not work in any different way, but it seems there's this huge barrier where you want to believe you're right. I can't dispel that so I bid you farewell.
I think official LTS for PHP would still help, if only to drive a few of the larger developers to target those versions to ensure maximum ease of deployment and maintenance.
In fact php with composer and tooling is really good these days. Most people I've met (in person) who hate on php can't say why. They tend to equate php with wordpress.
I've picked up their projects and see many problems but I don't go blame the language they chose.

PHP has made huge strides in progress over the last decade.
I challenge you to find PHP deployed in production in any Amazon service
Your reaction: "why do PHP devs get upset when ex-PHP users write false things about the language? Also, none of you know any other languages".
Thanks for the ad-hominem, that concludes this discussion.
Also, plenty of people who use PHP know so many other languages. You don't appear to be a professional in this industry, especially not with this kind of discourse.
Take care.
My comment was in response to you asking whether the other user (who as far as I can tell was not posting any false information about PHP, just pointing out that they personally preferred other languages?) wanted _recognition_, from you personally, for having learned some other language.
This is such a weird reaction to have to the idea that someone has learned, and/or would rather use, some other language. I hope you can see that.
Of course, it's not just you. I have never seen any programming language community that feels _threatened_ by the idea of other languages existing and being learned, in the way that the PHP community does.
Fundamentally, this is a learned social behaviour, which means that whether or not individual PHP developers know other languages does not matter. A community that treats acquiring additional knowledge as a _threat_, seeing learning from the outside world as a _betrayal_, will not be able to learn _from_ other languages.
As bringing new ideas and thoughts into the community is socially discouraged, it will only be possible for learning to flow in one direction: away from the PHP community.
For getting up and running, it saves time. For large projects, it adds leaky abstractions, overhead for each request, a need to upgrade another layer - with poor upgrade compatibility (in our anecdotal case), and very little gain. And it has it's own learning curve, which with modern PHP may be redundant.
Symfony looks better in that it is more of a library and less of a framework, though of course that has its own tradeoffs.
IMO, the weakest part of PHP is the db functions (both PDO and mysqli/postgres)
I asked what prompted the person to type that kind of reply. Had you read the entire topic, you'd see plenty of false info being posted, but my point remains: you used PHP, you moved on, what prompts you to be active in topic about PHP where all you contribute with is "I moved on."
> This is such a weird reaction to have to the idea that someone has learned, and/or would rather use, some other language. I hope you can see that.
And we're in territory of mental gymnastics now :)
You think the reaction is to learning another language? You're obviously a programmer. Can you tell me how many possible outcomes exist and how come you chose this one in particular?
Reaction was not to learning another language, it's ridiculous.
> I have never seen any programming language community that feels _threatened_
You never read linux mailing list and c vs c++? I can't take you seriously, you talk as if there exists de-facto "community". There isn't one, it's just a bunch of people who use various forums and there's no coherent community. You interacted with several people and you label that community and then you purposely shove words that haven't been written only to challenge them.
It's a straw man argument.
You persist in labeling PHP devs so narrow-minded that they chase away people who learn other languages. I don't know which (human) language I need to use, but it's apparent that this is becoming multiplayer monologue. I write one thing, you claim I wrote something else and then you generalize based on it.
Notice: I haven't tried to provide my "credentials" by listing what languages I know or what I do. I never even stated I'm a PHP dev.
You, on the other hand, labeled me and entire PHP community as weak-ego, tribalists who frown upon other languages and that the PHP community, which apparently you researched somehow, is different to all other communities - which you also apparently researched. In this whole wall of text you wrote, you have't asked a single question. You merely stated something and then you proceeded to take up the higher moral ground and then demean people. Do you think such discourse is productive?
> Fundamentally, this is a learned social behaviour, which means that whether or not individual PHP developers know other languages does not matter. A community that treats acquiring additional knowledge as a _threat_, seeing learning from the outside world as a _betrayal_, will not be able to learn _from_ other languages.
In this very topic, I wrote about features I'd like to see in PHP - one being generics. Something I learned in C# and something that changed my entire stance to JS because of having used in TypeScript.
That's just _one_ example of how you assume without zero facts to go by. I won't bother listing what we do for feature suggestions in PHP, which languages have great features and what we do to bring them in. You're just incapable of reading and you merely recognized me as a "bad guy" because I called someone out. I seriously doubt you'll read this, it would take more than 13 seconds of attention and that's something hard to acquire these days.
TL;DR: nice gaslighting and straw man, thanks for ad-hominem, I wish you well in the new year :)
I truly hope that this outlook on the world does you better than it did me when I was younger.
> Had you read the entire topic, you'd see plenty of false info being posted
I've honestly looked through all of the original poster's comments and couldn't find any misinformation. Except for referencing r/lolphp, which is indeed mostly wrong about everything.
> You think the reaction is to learning another language? [...] Can you tell me how many possible outcomes exist and how come you chose this one in particular?
I thought so, although I see now that I was wrong. I still don't understand what else your response, saying "Do you want recognition for learning other languages?" to a comment saying "I no longer use PHP and I have learned other languages that I actually like", was supposed to be reacting to, but I take it that there are other possible interpretations that I'm not grasping here.
> you talk as if there exists de-facto "community". [...] it's just a bunch of people who use various forums and there's no coherent community
Obviously a community as big as the PHP community is always going to be, in turn, fragmented into smaller communities. Symfony is not Laravel is not WordPress. But that doesn't mean that you can't draw generalisations from it, like how you would say "the Python community is scared of big breaking changes". This doesn't mean that every single member of that community is personally scared of big breaking changes. It's a generalisation about the behaviour of a group that doesn't extend into a judgement of each and every one of its members.
> You, on the other hand, labeled me and entire PHP community [...] which apparently you researched somehow
I thought there was no such thing as a PHP community. I described a general vibe that I perceive from a given community, which I have extensively interacted with and been a part of. Unless it doesn't exist, in which case I suppose I haven't.
I then compare it to other communities, which I have also interacted with and been a part of, if they indeed exist. My perception nonetheless may be flawed, and it does not need to apply to you specifically.
> I wrote about features I'd like to see in PHP
It's great that what I said above does not apply to you. Your personal appreciation of other programming languages' features, in turn, does not change what I perceive as the broader community's culturally enforced commitment to willful ignorance.
If I'm going to guess is that you have interacted with non-professional and/or beginner level PHP programmers, they could feel threatened becuase the only development skill they have is rudimentary PHP and you are asking them to replace that with something much more difficult. I have seen some of it myself, and it has always come down to lack of skill.
And this makes sense why you have encountered this within the larger PHP community, becuase PHP is an easy to learn beginner friendly language that is used by the majority of blog and forum systems, zero setup web frameworks, and all of it can be set into production on almost every server on earth. Thus there are many low skilled PHP developers, probably more than moth other languages.
And this is the lessons, it is important to understand that every community consist of large variety of disparate groups, especially within the PHP community, and it is up to you to learn to distinguish them. Unfortunately many are blind to this when it comes to the PHP community, outsiders may think the work I do professionally is the same as someone setting up blog for the first time, just because we use the same language. It would be same to think that the result of a first grader learning to write is the same thing as Tolkien's writings becuase both are in English.
Care to explain what you mean it's broken if disabled? That it is disabled (noop in runtime) so you're missing it? AFAIK that's the production setting. You should be able to enable it in build/test/ci/development, just how you want it.
There is benefit if you have the project under test and can run the build with different php versions thought. Best in parallel so you have current, next and future. It perhaps becomes the norm since the yearly release cycle but always was a requirement when supporting different php versions.
More than a LTS release I'd prefer more PHP 8 releases than the five in 7.x, e.g. more until 8.8 or 8.9.
I'm doing this quite often as I maintain some code-bases that have backward compat down to PHP 5.3 as the baseline. So if you're looking for forward compatibility of your PHP 5.6 codebase to 7.x and 8.x (incl. 8.2), its not so much of work.
If you need an upgrade tool, have different PHP versions at hand and load each file on the CLI and PHP will show you the deprecation warnings. It then depends a bit on the code (each()/next()/reset() family undergone some changes if not removals in 8? so you have to replace with some different syntax) but most of the rest is only deprecation warnings that can be overcome with #attributes "annotations" that are just comments prior php 8.
tooling could be better especially if you're running from low versions, thought. but using php on the cli directly brings you quite far and on speed already for most things in my personal experience. git, find and xargs are your friends.
That is for all but one version that is compiled from sources.
> but that's just Core. A lot of plugin developers are lightyears behind it seems.
How we train our dev's is to use those courses and to have our current PHP/Sugar dev mentor them on the differences.
Or even which of those companies even hire PHP devs anymore?
But that might just be me and/or my particular use case.
There is however a significant overhead to Docker. Building images takes time (and you will need to build your own, if you rely on any kind of PHP extension such as mbstring, etc) and just wrapping your head around everything is harder than people make it out to be.
That being said, I used to have my own set of bash scripts to setup local virtual hosts, databases, etc, and various strategies to keep configuration contained to single projects, but things always leaked out of the boxes I tried to put it in and in the end all those strategies failed.
So, my current estimate is that Docker doesn't save me much time, but it elevates the quality of the projects I'm working on. So overall I find it worth it to put in the effort to use Docker.
IIRC, the initial development was in the mid 2000s but it was abandoned several years later because they couldn't get Unicode support working correctly. By the time it was abandoned there was already a lot of material referencing it like books and conference talks. So when the PHP team decided to do a new major version most of the planned PHP 6 features were already added to 5.3 and 5.4 so they thought it best to just skip 6 to avoid confusion.
