If you get the following warning when using APCu functions via PHP's CLI SAPI:
PHP Warning: apcu_cache_info(): No APC info available. Perhaps APC is not enabled? Check apc.enabled in your ini file
then check the status of `apc.enable_cli`. This is a separate INI entry for enabling APC via the CLI SAPI.
