ADOdb Project on GitHub

ADOdb is a fast, easy to use, popular database abstraction layer for PHP. It allows the same code to be used when accessing a wide range of databases.

It has been actively maintained since 2000 by the project's founder, John Lim, who decided to retire from the project in 2013. Damien Regad and Mark Newnham took over the project, with the help of numerous community contributors.

ADOdb contains components for querying and updating databases, as well as an Object Orientated Active Record library, schema management and performance monitoring. It also contains the following standalone extensions:

  • A Date/Time library to handle dates outside of the normal PHP limits.
  • A Session Management library that extends the normal PHP functionality to allow storing of session management data in a database, or in encrypted values

Note that ADOdb is not a replacement for the native PHP database extensions, but is built on top of them. This means that the corresponding driver(s) must be installed and correctly configured for ADOdb to work.
