We won't be making this change. There are several reasons for this.

We only support the use of 1 abstraction library, for 16 it is a modded version of phpLib for 18+ it will be ADOdb with a wrapper.

PEAR DB is released under the PHP License and so is not GPL compatiable, and I have little interest in making major changes to suport non GPL compatiable code.

We use a modified versioon of phpLib's DB abstraction library, they had the namespace first

I would never make a change like this in stable, even if the first 3 problems didn't exist.

I suggest you use the supported abstraction libraries for your app.

I'm creating some custom modules for PHP-groupware and I like to use PEAR-DB in my modules.

But a nameclash between PEAR-DB and PHPgw's DB-class makes this very difficult. (PHPgw on my Debian terminates on loading PEAR-DB with: "Fatal error: Cannot redeclare class db in /usr/share/php/DB.php on line 271") I've seen many people complain about this problem in the newsgroups, but I've not seen any sollution for PHP-groupware so far.

After some research, I fixed this problem for myself by the following steps:

-rename [path_to_phpgw]/phpgwapi/inc/
to [path_to_phpgw]/phpgwapi/inc/

-change the class name 'db' to 'db_phpgw' at least in the following files:

-Replace "CreateObject('phpgwapi.db')" with "CreateObject('phpgwapi.db_phpgw')"
in the following files:

This is a very fundamental change, but I think the impact in PHPgroupware should not be too big, since only the framework and the setup scripts are supposed to create instances of PHPgroupware's db class. And personally I believe supporting PEAR-DB in the modules is worth this change.

My sollution only lasts until I upgrade my phpgroupware installation (when files mentioned above are overwritten), so I hope my sollution can help in finding a more permanent sollution for all people who build custom phpgroupware modules.

I'm currently using 'phpGroupWare API version' on Debian Unstable.
