opcache_is_script_cached — Tells whether a script is cached in OPCache
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 in-memory cache, not file cache. In order to check file cache, use opcache_is_script_cached_in_file_cache().
