Procedural style

bool mysqli_set_charset(mysqli link,
                        string charset);

Parameters

link

Procedural style only: A link identifier returned by mysqli_connect or mysqli_init

charset

The charset to be set as default.

Notes

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.

Examples

Example 3.66 mysqli::set_charset example

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();
?>

   

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);
?>

   

The above examples will output:


Current character set: utf8
