Subject Re: Using events with php

Am I correct in understanding that you want to pass arguments with your event? As far as I know this is not possible. If you send a RAW:1234 event you need to register in PHP to receive RAW:1234 event. You can't listen for RAW:* event (like wildcards).

You can send a generic RAW event and in the trigger add a recently changed field so you can retrieve the recently changed records. See for an explanation here:
Is it possible to use arguments with firebird events : POST_EVENT 'event_name' + string args?
