PHP is often a good business decision because there is no shortage of affordable devs to help manage the code. If you're building a small, low-margin business, it may be the best choice. I hate writing PHP btw.
While this is obviously location dependent, over the last year or so I've had dozens of calls from recruiters asking me to come work on PHP (mostly Symfony and Laravel) applications, and telling me they just can't find competent senior and lead devs.
