printf("Connect failed: %s\n", mysqli_connect_error());
exit();

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

Коментарии
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;
?>
