It allows subjects to trigger events that observers can process if they're interested, or better yet, completely ignore. This allows standardized code bases to create nice hooks that allow extensibility without needing to place one-off code inside the main project. A quick example might be on saving a record in your code, it triggers an event, then an observer in a custom site watches for said event and injects/updates a search entry in Lucene. This way one site can have a custom search engine that another site might not need. I started off with the concepts I found in http://examples.stubbles.net/docroot/events/ but created my own because I wanted something stand-alone. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
