oikai_using_opcache() – Check to see if opcache is being used

Description

Check to see if opcache is being used

If it is then we will not be able to read the docblock using $refFunc->getDocComment() against a function which is already loaded. Instead we use the dummy load and reflect technique Prior to PHP 5.5.5 we can't find out anything about opcache so we have to make it up. WP Engine sets some constants which we might be able to use BUT what we'll actually do is to see if we can get our own docBlock written right here.

Usage

$bool = oikai_using_opcache();

Parameters

Returns

bool true if we believe that opcache processing is being used
