mysqli_report(int $flags): true

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.

try {
/* if the connection fails, a mysqli_sql_exception will be thrown */
$mysqli = new mysqli("localhost", "my_user", "my_password", "my_db");

/* this query should report an error */
$result = $mysqli->query("SELECT Name FROM Nonexistingtable WHERE population > 50000");

/* this query should report a bad index if the column population doesn't have an index */
$result = $mysqli->query("SELECT Name FROM City WHERE population > 50000");
} catch (mysqli_sql_exception $e) {
error_log($e->__toString());
}

/* this query should report an error */
$result = mysqli_query($link, "SELECT Name FROM Nonexistingtable WHERE population > 50000");

/* this query should report a bad index if the column population doesn't have an index */

/* this query should report an error */
$result = $mysqli->query("SELECT Name FROM Nonexistingtable WHERE population > 50000");

/* this WILL NOT report any errors even if index is not available */

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;

?>
