(PHP 5 >= 5.0.5)
mysqli::set_charset -- mysqli_set_charset — 设置默认字符编码
面向对象风格
$charset
)过程化风格
设置在数据库间传输字符时所用的默认字符编码。
成功时返回 TRUE， 或者在失败时返回 FALSE。
Note:
如果在Windows平台上使用该方法，需要4.1.11版或以上的MySQL客户端库，且MySQL版本为5.0.6以上。
Note:
这应该是首选的用于改变字符编码的方法，不建议使用 mysqli_query()执行SQL请求的SET NAMES ...（如 SET NAMES utf8）。 详见MySQL字符集的概念
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

On windows, with "stock" PHP 5.1.2, there is no set_charset function at all. One may have to replace php_mysqli.dll, and libmysql.dll with proper versions, which provided by MySQL at http://dev.mysql.com/downloads/connector/php/
