link仅以过程化样式：由 mysqli_connect() 或 mysqli_init() 返回的链接标识。
charset
The charset to be set as default.
成功时返回 TRUE， 或者在失败时返回 FALSE.
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 set it (such as SET NAMES utf8) is not recommended. See the MySQL character set concepts section for more information.
Example #1 mysqli::set_charset() example
面向对象风格
<?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();
?>
过程化风格
<?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);
?>
以上例程会输出：
Current character set: utf8
