I spent about a year writing PHP, and I thought it was a fun language. You can write very compact code in it, I could write it fast, and I seldom had to do any difficult debugging.
I saw some really bad PHP written by other people. But that shows how easy it is to write. Even people who are terrible at programming can figure it out, sort of.
So far I've got necessity, and maybe that's the whole story, maybe not.
I'd really like somebody to say "because I like to" - that's the conversation I really want to have. I would love to know why someone would say that, and not because I'm a troll, but because I do not like PHP at all and I have genuinely have no way of answering that question on my own.
