With or without the M doesn't work for me. Regardless of what I put, apc.php still shows a shm size of 32M. I have the current version of apc and php 5.4.36 – shaiss Feb 12 '15 at 2:13. Alternative PHP Cache (APC) stores the bytecode of previous PHP compilations so we do not need to recompile every time thereby saving time. We have to clean the cache entries for a fresh compilation. For this purpose, we can use the PHP function apcclearcache to remove cache entries. This command clears the cache and returns “true” on.
If backward compatibility with the applicable parts of APC is required, APCu must be configured with the option --enable-apcu-bc.Warning
PHP 7 has a separate module (» apc.so) for backwards compatibility with APC. Windowskernelmodedriver10 0.
In backward compatibility mode, APCu registers the applicable APC functions with backward compatible prototypes.
Where an APC function accepted
cache_type, it is simply ignored by the backward compatible version, and omitted from the prototype for the APCu version.
Note: On Windows, APCu needs a temp path to exist, and be writable by the web server. It checks the TMP, TEMP and USERPROFILE environment variables in that order and finally tries the WINDOWS directory if none of those are set.
