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.
