mysqli::set_charset -- mysqli_set_charset — Sets the default client character set
Object oriented style
$charset
) : boolProcedural style
Sets the default character set to be used when sending data from and to the database server.
linkProcedural style only: A link identifier returned by mysqli_connect() or mysqli_init()
charsetThe charset to be set as default.
Returns TRUE on success or FALSE on failure.
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
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();
}
printf("Initial character set: %s\n", $mysqli->character_set_name());
/* change character set to utf8 */
if (!$mysqli->set_charset("utf8")) {
printf("Error loading character set utf8: %s\n", $mysqli->error);
exit();
} else {
printf("Current character set: %s\n", $mysqli->character_set_name());
}
$mysqli->close();
?>
Procedural style
<?php
$link = mysqli_connect('localhost', 'my_user', 'my_password', 'test');
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
printf("Initial character set: %s\n", mysqli_character_set_name($link));
/* change character set to utf8 */
if (!mysqli_set_charset($link, "utf8")) {
printf("Error loading character set utf8: %s\n", mysqli_error($link));
exit();
} else {
printf("Current character set: %s\n", mysqli_character_set_name($link));
}
mysqli_close($link);
?>
The above examples will output something similar to:
Initial character set: latin1 Current character set: utf8
