Invoking a PHP script from a MySQL trigger

Question

Is there any way how to invoke a PHP page / function when a record is inserted to a MySQL database table? We don\'t have control over the record insertion procedure. Is ther

Answer 1

I was thinking about this exact issue for a case with long polling where I didn't want the php script to have to continually poll the db. Polling would need to be done somewhere, memory would probably be best. So if somehow the trigger could put the info into something like memcache, then php could poll that would would be much less intensive overall. Just need a method for mysql to use memcache. Perhaps into a predefined variable with a specific user id. Once the data is retrieved php could reset the var until the db sets it again. Not sure about timing issues though. Perhaps a second variable to store the previous key selected.
