Clearing the cache from an external PHP script

  • Hi, I’d like to clear the W3tc cache via an external php script.

    My understanding is that this should work. In fact, it works when WP Super Cache is enabled, but not when W3TC is enabled.

    Any pointers?

    define( 'WP_USE_THEMES', false );
require('wp-blog-header.php');

	if ( function_exists('w3tc_pgcache_flush') ) {
		w3tc_pgcache_flush();
	} else if ( function_exists('wp_cache_clear_cache') ) {
		wp_cache_clear_cache();
		}

    Also, it does not work if I use this, instead of wp-blog-header.php:

    require('wp-load.php');

    Also, I have “Page Cache (disk advanced)” enabled ONLY. No other caches enabled.

    Does function_exists('w3tc_pgcache_flush') evaluate to true?

    If so, how do you checking that it doesn’t work?

    Thanks WIllie. It seems as though the user account under which the external php script runs matters. It works when I run as root, but not as a regular user.
