[Info Request] PHP Call to Clear Cache

Hey guys, is there a PHP function that I can call that will clear the plugins cache?

Scenario:
I’ve got autoptimize installed alongside this plugin (they work really well together!)

I have a custom function that auto clears my autoptimize cache when it gets over a pre-defined size. Previously it was configured to sit in with “W3 TC” and auto clear W3TC Cache.

However, I’m having better results with Cache Enabler, and just love the webp feature! and would like to update this function so that both caches are cleared together.

Any assistance you guys could provide me is as always greatly appreciated!

With kind and warm regards
Lee
