Automatically Purge

Hello,
I have some code that may or may not flush the cache automatically and wanted to check with you folks first. I am not sure it will work and I don’t want to corrupt my functions.php file.

// Scheduled Action Hook
 
function w3_flush_cache( ) {
	$w3_plugin_totalcache->flush_all();
}
 
// Schedule Cron Job Event
 
function w3tc_cache_flush() {
	if ( ! wp_next_scheduled( 'w3_flush_cache' ) ) {
		wp_schedule_event( current_time( 'timestamp' ), 'daily', 'w3_flush_cache' );
  }
}
add_action( 'wp', 'w3tc_cache_flush' );
