The phpGrid v7 can support "native" DB2 driver, which probably has better performance. Hence, it is preferable.
If you also need to use the DB2 connection options (See http://php.net/manual/en/function.db2-connect.php) such as i5_naming, i5_lib, etc, it will need one simple update in the database class 'cls_db.php' to include one additional parameter array that is DB2 specific.
The update is now available to paid customers. Please contact support to acquire the update.
