Chapter 3: Introduction to Connections 27
Examples
Example 1. Connect to database through a socket
mysql://user@unix(/path/to/socket)/pear
Listing
3-4
Example 2. Connect to database on a non standard port
pgsql://user:pass@tcp(localhost:5555)/pear
Listing
3-5
If you use, the IP address 127.0.0.1, the port parameter is ignored (default: 3306).
Example 3. Connect to SQLite on a Unix machine using options
sqlite:////full/unix/path/to/file.db?mode=0666
Listing
3-6
Example 4. Connect to SQLite on a Windows machine using options
sqlite:///c:/full/windows/path/to/file.db?mode=0666
Listing
3-7
Example 5. Connect to MySQLi using SSL
mysqli://user:pass@localhost/pear?key=client-key.pem&cert=client-cert.pem
Listing

Opening New Connections
Opening a new database connection in Doctrine is very easy. If you wish to use PDO 19 you
can just initialize a new PDO object.
Remember our bootstrap.php file we created in the Getting Started (page 18) chapter?
Under the code where we registered the Doctrine autoloader we are going to instantiate our
new connection:
// bootstrap.php
Listing
3-9
// ...
$dsn = 'mysql:dbname=testdb;host=127.0.0.1';
$user = 'dbuser';
$password = 'dbpass';
$dbh = new PDO($dsn, $user, $password);
$conn = Doctrine_Manager::connection($dbh);
Directly passing a PDO instance to Doctrine_Manager::connection() will not allow
Doctrine to be aware of the username and password for the connection, since their is no
way to retrieve it from an existing PDO instance. The username and password is required
in order for Doctrine to be able to create and drop databases. To get around this you can
manually set the username and password option directly on the $conn object.
// bootstrap.php
