$charset = $mysqli->character_set_name();
echo "當前連接的字符集為: " . $charset;

$mysqli = new mysqli("localhost", "username", "password", "database_name");

if ($mysqli->connect_error) {
    die("連接失敗: " . $mysqli->connect_error);
}

$charset = $mysqli->character_set_name();
echo "當前連接的字符集為: " . $charset;

$mysqli->close();
