[DataObjects] - Multiple DB Join

Hi I want to connect to multiple database within DO and do a join on tables within. The documentation states: -- When you have multiple databases you can use the database_* to specify the DSN for each database Example 33-5. using multiple databases - database passwords database_authentication = mysql://user:password@localhost/authentication

database_sales           = mysql://user:password@localhost/sales

-- Now how do I do this if I am using the ini method : ? The below obviously takes the last DB called. $config = parse_ini_file('authentication.ini',TRUE); foreach($config as $class=>$values) {

    $options = &PEAR::getStaticProperty($class,'options');
    $options = $values;

} $config = parse_ini_file('sales.ini',TRUE); foreach($config as $class=>$values) {

    $options = &PEAR::getStaticProperty($class,'options');
    $options = $values;

} A little bit stuck on this, I havent really figured out how to get the best from the Docs available on Pear site. Ian
