Oracle & PHP users: make sure you check out the Zend Conference. I'll be given a couple of sessions, "Connection Pooling & Other Features for Data Scaling" and "Performance Tuning for PHP with Oracle Databases". There are plenty of other great talks, too.
There's tons of other sessions happening during the conference including talks on:
- best practices
- enterprise PHP
- the Zend Framework
- API design
Check out the official conference page for information on location, other sessions and registration.
