Symfony database connection without using database.yml

Question

Let's say you have a situation where your Symfony application cannot get its database connection information from the databases.yml file.

In this situation, how can you set up a database connection "by hand" (let's assume Doctrine as the ORM)?

Answer 1

Maybe use "Opening New Connections"

// bootstrap.php

// ...
$dsn = 'mysql:dbname=testdb;host=127.0.0.1';
$user = 'dbuser';
$password = 'dbpass';

$dbh = new PDO($dsn, $user, $password);
$conn = Doctrine_Manager::connection($dbh);
