That has not been my experience. When I used to work with that tech stack, the major framework choice only ever had 3 options:
Zend Framework, Symfony and Laravel.
From what I hear Laravel is the industry leading and there's no sign of that changing.
Sure there are other less popular frameworks just like in other languages.

PHP have had a published standard specification for framework and component interoperability for long time now:
