Upgrade 6.37->7.41 = settings.php echoed on WSOD

Trying to upgrade from 6.37 to 7.41. After following all of the steps and running update.php, all i get is a WSOD with the output of my settings.php on the screen
Don't see any errors in the apache logs.

Can't seem to get past this - any help/info/wisdom appreciated.

This is what the WSOD displays:

$databases = array ( 'default' => array ( 'default' => array ( 'driver' => 'mysql', 'database' => 'XYZ', 'username' => 'XYZ', 'password' => 'abc123', 'host' => 'localhost', 'port' => '', 'prefix' => '', ), ), ); $drupal_hash_salt = 'xxxxxxxxxxxxxxx';
