I don't know which planet you're living on but all you need to do is search Indeed.com for title:php and you'll find PHP is up there with Java, C# and Javascript in terms of the number of jobs. In some countries Java, JS and PHP are the only languages used in any significant numbers. Likewise in more technologically advanced countries once you get away from the tech hubs. I'm not a fan of PHP and I wish it was true but dead it certainly ain't.
