Can someone please explain / refer me to the php documentation regarding the meaning/use of "(string)" in the following:

		// Do not serialize the $hooks because they might contain non-serializeable objects
		$key = (string) $dsn_or_conn . serialize($config) . $log_level;

It's a cast (conversion) to make the $dsn_or_conn . serialize($config) . $log_level a string.
