I've updated the old Oracle PHP FAQ and the Oracle PHP Troubleshooting FAQs that were hosted by Oracle Technology Network (OTN). We've redirected the old FAQ pages to a new wiki page: http://wiki.oracle.com/page/PHP+Oracle+FAQ with the updated content. Feel free to create an account and make updates. Hosting the FAQ on a wiki seems appropriate because PHP is open source and grows by the value of everyone's contributions.
Questions so far include some of the basics (connecting, querying, etc) and a few more complicated issues like pre-fetching, LOBS and new information for using the Zend Server to connect to your Oracle databases.
