Sadly, there's so much LAMP stuff in enterprise including core apps and CMSes, that it's going to hang around like COBOL and FORTRAN zombies forever. Statamic, Facebook, Asana and many other startups with seemingly "lower"-technical investments reach for Linux, Apache HTTPd, MySQL and PHP because they are?/were? as pervasive as JavaScript and HTML. The bigger and older the business, the more complexity and more legacy bits there's going to be... heck, there's still operational DC electric utility companies in SF and NYC for elevators running since the time of Edison & Telsa. I would bet Java and C# will also hang indefinitely around too. It takes ballsy but careful technical leadership to standardize and phase-out crunchy legacy systems like mainframes with suitable modern replacements.
