PHP isn’t something I ever want to touch again (its libs are wonky and I dislike the syntax choices of the last years) but the execution model was sort of nice before the frameworks (an entry point with a clean state you can work yourself through).
The statistics are a bit misleading though. Just because 80% of the sites run PHP in some way doesn’t mean there are that many Jobs. A lot of the work with PHP world is not necessarily going to be PHP work (a lot of HTML, JavaScript and Plugin configuration) and there is complexity in learning your way around a system well enough to build plugins. The jump from beginner to expert has become harder for a new PHP programmer because the real programming is hidden behind a wall of already existing code that just needs to be installed, configured and customized.
I’m glad I got out when I did because I get to actually program APIs and Single Page Apps rather than just being a glorified PHP webpage mechanic.
