Depending on the flags, it sets mysqli error reporting mode to exception, warning or none. When set to MYSQLI_REPORT_ALL or MYSQLI_REPORT_INDEX it will also inform about queries that don't use an index (or use a bad index).

As of PHP 8.1.0, the default setting is MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT. Previously, it was MYSQLI_REPORT_OFF.
