Real Time Event Listener for PHP and mySQL
===

I am thinking of implementing a real time event listener for a personal project. Is there are way that say, if an `INSERT`, `UPDATE`, and `DELETE` SQL queries have been issued, then mySQL will trigger a PHP file which will in turn process this, like refreshing a page automatically if a new record is found, or say a record has been edited or deleted?

I have been reading through mySQL triggers but I do not know how to implement. Thanks!
