For those who are frustrated that PHP is now handling your SQL errors it's actually buried here:
https://www.php.net/mysqli_report
Specifically:
https://www.php.net/manual/en/mysqli.constants.php#constant.mysqli-report-off
Which is ironic. Yes, there is some validity to trying to centralize all error reporting regardless of the source of the errors but if you're like me with ~1,500 instances of SQL queries it's not at the top of your to-do list (especially with how much technical debt many people have on top of client demands).
Simply add this along with your other error reporting settings:
<?php
//Prevents PHP from handling SQL errors:
mysqli_report(MYSQLI_REPORT_OFF);
?>
If you're starting a new project or have way too much time on your hands then I'd agree you're in a better position to try to merge all of the error reporting. Choose wisely and good luck!
