Anmerkungen
Hinweis: 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).

Beispiele
Beispiel #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();
?>Beispiel #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);
?>Das oben gezeigte Beispiel erzeugt folgendeAusgabe:
Current character set: utf8
