Definiert in:

Removes a function from a specified filter hook.

This function removes a function attached to a specified filter hook. This method can be used to remove default functions attached to a specific filter hook and possibly replace them with a substitute. To remove a hook, the $function_to_remove and $priority arguments must match when the hook was added. This goes for both filters and actions. No warning will be given on removal failure.

	$r = false;

		if ( ! $wp_filter[ $tag ]->callbacks ) {
			unset( $wp_filter[ $tag ] );
