Note:

To use this function on a Windows platform you need MySQL client library version 4.1.11 or above (for MySQL 5.0 you need 5.0.6 or above).

Note:

This is the preferred way to change the charset. Using mysqli::query() to execute SET NAMES .. is not recommended.

面向对象风格

 1 <?php
 2 $mysqli = new mysqli("localhost", "my_user", "my_password", "test");
 3 
 4 /* check connection */
 5 if (mysqli_connect_errno()) {
 6     printf("Connect failed: %s\n", mysqli_connect_error());
 7     exit();
 8 }
 9 
10 /* change character set to utf8 */
11 if (!$mysqli->set_charset("utf8")) {
12     printf("Error loading character set utf8: %s\n", $mysqli->error);
13 } else {
14     printf("Current character set: %s\n", $mysqli->character_set_name());
15 }
16 
17 $mysqli->close();
18 ?>

 

过程化风格

 1 <?php
 2 $link = mysqli_connect('localhost', 'my_user', 'my_password', 'test');
 3 
 4 /* check connection */
 5 if (mysqli_connect_errno()) {
 6     printf("Connect failed: %s\n", mysqli_connect_error());
 7     exit();
 8 }
 9 
10 /* change character set to utf8 */
11 if (!mysqli_set_charset($link, "utf8")) {
12     printf("Error loading character set utf8: %s\n", mysqli_error($link));
13 } else {
14     printf("Current character set: %s\n", mysqli_character_set_name($link));
15 }
16 
17 mysqli_close($link);
18 ?>

 

以上例程会输出：

Current character set: utf8
