'; echo "

步骤二：调用 character_set_name 方法

"; echo "

在成功建立连接后，可以直接调用 character_set_name() 方法获取当前连接使用的字符集：

"; echo '

$charset = $mysqli->character_set_name();
echo "当前连接的字符集为: " . $charset;

'; echo "

步骤三：示例输出

"; echo "

完整示例代码如下：

"; echo '

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

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

$charset = $mysqli->character_set_name();
echo "当前连接的字符集为: " . $charset;

$mysqli->close();

'; echo "
