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.
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.
