Your DSN is invalid. As documented in the PHP manual the DSN prefix should be oci: like so:

'dsn'   => 'oci:dbname=(DESCRIPTION =
                (ADDRESS = (PROTOCOL = TCP)(HOST = MY HOST NAME)(PORT = 1521))
                (CONNECT_DATA =
                  (SERVER = DEDICATED)
                  (SERVICE_NAME = orcl)
                )
              )',

I would, however, recommend using the 'EZCONNECT' syntax as this doesn't clutter your code:
