面向对象风格

<?php
$mysqli
= new mysqli("localhost", "nobody", "");

/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}

if (!
$mysqli->query("SET a=1")) {
print_r($mysqli->error_list);
}

/* close connection */
$mysqli->close();
?>

过程化风格

<?php
$link
= mysqli_connect("localhost", "my_user", "my_password", "world");

/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}

if (!
mysqli_query($link, "SET a=1")) {
print_r(mysqli_error_list($link));
}

/* close connection */
mysqli_close($link);
?>

以上示例会输出:

            [sqlstate] => HY000
            [error] => Unknown system variable 'a'
