mysqli_set_charset

(PHP 5 >= 5.1.0RC1)

mysqli_set_charset

(no version information, might be only in CVS)

mysqli->set_charset -- Sets the default client character set

Description

bool mysqli_set_charset ( mysqli link, string charset )

The mysqli_set_charset() function sets the default character set (specified by the charset parameter) to be used when sending data from and to the database server represented by the link parameter.

注: 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)

返回值

如果成功则返回 TRUE，失败则返回 FALSE。

参见

mysqli_character_set_name() 和 mysqli_real_escape_string().

范例

例子 1. 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();
?>

例子 2. 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

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/
