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:
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.
ADOdb is compatible with and supported on all active versions of PHP (>= 7.2 as of this writing).
It is expected to work as well on earlier versions (PHP 5.3 or later), but this is not officially supported. See PHP 7 status.

We have limited resources, and unfortunately can't afford to maintain the older versions in parallel with the current stable releases and the development track.
Version 5.20.0 was released in November 2015, you should be at least to that point, and we strongly recommend to apply the latest hotfix release..
The ADOdb user base is large, with an average of 300 downloads a week. We have put together a short list of some current projects. See also the dependencies, i.e. the list of GitHub repositories require ADOdb in their composer.json file.
