Example #1$mysqli->error_listexample

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);
?>

以上例程会输出：

    [0] => Array
        (
            [errno] => 1193
            [sqlstate] => HY000
            [error] => Unknown system variable 'a'
        )
