Connect oracle with pdo, with SID and INSTANCE_NAME
How do I connect to Oracle using PDO::__construct().
What I have are the host, port, SID and INSTANCE_NAME.
Looking for information I have founded
at http://docs.oracle.com/cd/E18283_01/network.112/e10836/naming.htm#i498306, but I don't know how to "translate" it to PDO.
And see http://www.php.net/manual/en/ref.pdo-oci.connection.php for more info. The username is passed separately.
