There's still lots of small-fish web development agencies who specifically hire PHP developers. That's about it though, I think the web development industry is specifically tied to PHP because of their excessive dependence on WordPress, Drupal etc, this also produces developers who are overly specialised in niches using these platforms at the expense of general capability. Think back to the mid-2000's where there was a big difference between a JavaScript developer and a jQuery developer - while they both wrote JS the latter was generally incapable of using vanilla JS proficiently because their use of jQuery's abstractions as a crutch impaired their learning of the underlying fundamentals. A lot of "WordPress developers" are so heavily specialised in using WordPress they probably can't even remember how to write a vanilla PHP site.
