Object-oriented style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "test");
printf("Initial character set: %s\n", $mysqli->character_set_name());
/* change character set to utf8mb4 */
$mysqli->set_charset("utf8mb4");
printf("Current character set: %s\n", $mysqli->character_set_name());
Procedural style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect('localhost', 'my_user', 'my_password', 'test');
printf("Initial character set: %s\n", mysqli_character_set_name($link));
/* change character set to utf8mb4 */
mysqli_set_charset($link, "utf8mb4");
printf("Current character set: %s\n", mysqli_character_set_name($link));
The above examples will output something similar to:
Initial character set: latin1 Current character set: utf8mb4
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.
