ezSQL is an open source PHP database class that I wrote a while back. It’s used on over 100k websites and is the backbone of many open source projects such as WordPress. The class makes it ridiculously easy to use mySQL, Oracle8, SQLite (PHP), within your PHP script. Includes lots of examples making it very easy to understand how to work with databases. ezSQL has excellent debug functions making it lightning-fast to see what’s going on in your SQL code. ezSQL can dramatically decrease development time and in most cases will streamline your code and make things run faster.
