[http://pear.php.net/package/MDB2 PEAR::MDB2] is a merge of the PEAR::DB and Metabase php database abstraction layers.

* Datatype abstraction and on demand datatype conversion
* Portable error codes
* Sequential and non sequential row fetching as well as bulk fetching
* Ability to make buffered and unbuffered queries
* Ordered array and associative array for the fetched rows
* Prepare/execute (bind) emulation
* Sequence emulation
* Replace emulation
* Limited Subselect emulation
* Row limit support
* Transactions/Savepoint support
* Large Object support
* Index/Unique support
* Module Framework to load advanced functionality on demand
* Table information interface
* RDBMS management methods (creating, dropping, altering)
* RDBMS independent xml based schema definition management
* Altering of a DB from a changed xml schema
* Reverse engineering of xml schemas from an existing DB
* Full integration into the PEAR Framework
