紧急求助--谁帮我看看这个PHP程序的数据库连接怎么配置!

<?php
/**
* ADOdb Lite Configuration File
*/
/**
* Set the $dbtype variable to the database designator.
* If this variable is enabled it will override the database designator
* entered in the ADONewConnection( $dbtype ) function. The database
* designator in a DSN string will be overridden but the rest of the DSN
* string will be used.
*
* You can place a DSN entry in the $dbtype variable if you would like to
* auto connect to your database.
*
* Example:
*
* $dbtype = \"driver://username:password@hostname/database?options[=value]#modules\";
*
* driver = Databasetype Designator listed in the table at the start of this page.
* username = The Username needed to access the database
* password = Optional password for accessing the database
* hostname = localhost or url/ip address IE: http://0.0.0.0 or http://www.dbserver.com
* database = The name of the database you will be accessing
* options = All Drivers - \'persist\', \'persistent\', \'debug\', \'fetchmode\'
*                      Mysql (all) - \'port\', \'clientflags\'
*                      Mysqli - \'socket\'
*                      Postgress (all) - \'port\'
* modules = The modules that should be loaded. IE: pear, cache, extend, ect.
*
*/
$dbtype = \"mysql://gbb3333:gbb3333@localhost/gbb3333\";
/**
* If you want to maintain compatability with the ADOdb ADONewConnection( $dbtype )
* function you should designate the modules you need loaded below. If you designate
* the modules below you do not need to designate them in
* ADONewConnection( $dbtype, $modules ).
*
* If you would like more than one module loaded at the same time concatinate the
* module names using a colon (:).
*
* Example:
* $modules = \"pear:transaction:extend\";
*
* The above example would load the Pear, Transaction and Extend modules
* automatically.
*/
// $modules = \"pear\";
