We are working to ensure full support for PHP 7 in both the current ADOdb production (5.20.x) , and development (5.21.x) releases. There are no plans to implement PHP 7 support in ADOdb version 5.19.

Any PHP 7 compatibility issues found are released as Hot-fixes to the current production release, so it is important that you use the most recent version. Hot-fix releases are drop-in replacements to earlier versions of the same release number. You can check the current status of PHP 7 issues on the Github Issues Tracker.

Users have reported that upgrading from releases 5.00 (released in 2007) and higher have been reasonably easy, but that earlier versions may require substantial adjustments, due to design considerations in ADOdb version 4. If you need guidance, use any of the support methods listed on the main page.

In order to migrate their products from custom older versions of ADOdb back to the core product and take advantage of the active development of the product, as well as PHP 7 compatibility, a number of users have submitted their custom functionality to be integrated into core. If you are in the same situation, contact us about having your feature added.
