Examples
Example #1 Object-oriented style
<?php
/* activate reporting */
$driver = new mysqli_driver();
$driver->report_mode = MYSQLI_REPORT_ALL;
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());
}

try {
/* if the connection fails, a mysqli_sql_exception will be thrown */
$link = mysqli_connect("localhost", "my_user", "my_password", "my_db");
/* 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 */
$result = mysqli_query($link, "SELECT Name FROM City WHERE population > 50000");
} catch (mysqli_sql_exception $e) {

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