Description: ------------ When handling connection exceptions, Doctrine DBAL uses the mysqli::$sqlstate property of the connection. Prior to PHP 8, access to the property of a non-initialized connection would result in a warning and returned false: In PHP 8 the warning got promoted to a fatal error. There doesn't seem to be a way to see if the connection is initialized, so it might make sense to just return false there and not raise an error. Additionally, the possible false value of the property is not documented in https://www.php.net/manual/en/class.mysqli.php which leads to false-positive issues during static analysis. Test script: --------------- var_dump(mysqli_init()->sqlstate); Expected result: ---------------- false Actual result: -------------- Fatal error: Uncaught Error: Property access is not allowed yet PatchesPull RequestsHistoryAllCommentsChangesGit/SVN commits

Well, the Error can be caught: <?php try { var_dump(mysqli_init()->sqlstate); } catch (Error $e) { echo $e->getMessage(), PHP_EOL; } ?> Still, it may make sense to introduce a function for checking whether a mysqli instance is connected.
