<simpara>
This function checks if a PHP script has been cached in OPCache. This can be
used to more easily detect the "warming" of the cache for a particular script.
This function only checks file cache cache, not in-memory cache. In order to
check in-memory cache, use <function>opcache_is_script_cached</function>.
