A lot of people are too proud to be associated with PHP. I am ready to admit that know nothing about the language except that a lot of people make cool things with it.
My favourite PHP product at the moment is BookStack (https://www.bookstackapp.com/), a really good wiki. I run an instance for my family and it's great.
But there are loads of things. And I notice that many of the sites I like using...are built on well maintained PHP stacks.
