Hi,

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/class.db.inc.php
 to     [path_to_phpgw]/phpgwapi/inc/class.db_phpgw.inc.php

-change the class name 'db' to 'db_phpgw' at least in the following files:
  [path_to_phpgw]/phpgwapi/inc/class.db_mysql.inc.php
  [path_to_phpgw]/phpgwapi/inc/class.db_pgsql.inc.php
  [path_to_phpgw]/phpgwapi/inc/class.db_oracle.inc.php
  [path_to_phpgw]/phpgwapi/inc/class.db_mysql.inc.php
  [path_to_phpgw]/phpgwapi/inc/class.db_sapdb.inc.php
  [path_to_phpgw]/phpgwapi/inc/class.db_[db_you_actually_use].inc.php

-Replace "CreateObject('phpgwapi.db')" with
"CreateObject('phpgwapi.db_phpgw')"
 in the following files:
   phpgwapi/inc/class.setup.inc.php
   phpgwapi/inc/functions.inc.php

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 0.9.16.005' on Debian
Unstable.

Regards,
Peter van der Meer
