范例

例 1326. Object oriented style

<?php
$mysqli
= new mysqli("localhost", "my_user", "my_password", "test");

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

/* change character set to utf8 */
if (!$mysqli->set_charset("utf8")) {
   
printf("Error loading character set utf8: %s\n", $mysqli->error);
} else {
   
printf("Current character set: %s\n", $mysqli->character_set_name());
}

$mysqli->close();
?>

例 1327. Procedural style

<?php
$link
= mysqli_connect('localhost', 'my_user', 'my_password', 'test');

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

/* change character set to utf8 */
if (!mysqli_set_charset($link, "utf8")) {
   
printf("Error loading character set utf8: %s\n", mysqli_error($link));
} else {
   
printf("Current character set: %s\n", mysqli_character_set_name($link));
}

mysqli_close($link);
?>

上例将输出:

Current character set: utf8
