If this function is run from the CLI it will clear the command line cache only.
To clear the http cache you need to put this in a PHP script and run it via a http:// URL.

Looking at the APC source, apc_clear_cache() only recognizes "user" as a cache_type. If cache_type is omitted, or any other string (including "opcode") is provided, the effect is to clear the system cache.

It appears for me in PHP 5.2.11/APC 3.1.2 that to clear the opcode cache the argument must be 'opcode'. Having no argument seems to have no effect.
