过程化风格

mysqli_report(int $flags): bool

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.

Seems not clear but flags *could be combined*, as per other flags.
For example:

<?php

# wannabe noticed about all errors except those about indexes
$driver = new mysqli_driver();
$driver->report_mode = MYSQLI_REPORT_ALL & ~MYSQLI_REPORT_INDEX;

?>

As a recommendaton on memory management please don't use the objective way your creating an object to specify one property and thats all your doing with it, much more effective both for the parser and for memory to use the proccedual style for setting the report flag.
