### 설명

Object oriented style (method):

bool mysqli::set_charset ( string `$charset` )

Procedural style:

bool mysqli_set_charset ( mysqli `$link` , string `$charset` )

Sets the default character set to be used when sending data from and to the database server.

### 인수

`link`

  순차 형식 전용: mysqli_connect()나 mysqli_init()가 반환한 연결 식별자.

`charset`

  The charset to be set as default.

### 반환값

성공할 경우 `TRUE`를, 실패할 경우 `FALSE`를 반환합니다.

### 주의

> 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 execute SET NAMES .. is not recommended.

exit();
}
/* change character set to utf8 */
if (!$mysqli->set_charset("utf8")) {
printf("Error loading character set utf8: %s\n", $mysqli->error);
} else {
