mysql_connect and PHP 5.0

I've installed MySQL 5.0 with Apache 2.0.50. Before, I had running MySQL 4.3.3 and 2.0.47 and a Picturegalerie. After migrating to 5.0 i get this error: Call to undefined function mysql_connect() in D:\kreiszner\galerie\includes\db_mysql.php on line 39 This is line 39 and 40: if (!$this->connection = $connect_handle($db_host, $db_user, $db_password)) { $this->error("Could not connect to the database server ($db_host, $db_user).", 1); } Whats wrong????
