我改变了函数名称，但仍然得到这个不能重新声明geting_Ip（）（之前在C：\ xampp \ htdocs中声明）

Question

function geting_Ip() {
    $ip = $_SERVER['REMOTE_ADDR'];

    if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
        $ip = $_SERVER['HTTP_CLIENT_IP'];
    } elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    }

    return $ip;
}
