PHP个人常用函数封装

function GetIP(){
    if(!empty($_SERVER["HTTP_CLIENT_IP"])){
          $cip = $_SERVER["HTTP_CLIENT_IP"];
    }elseif(!empty($_SERVER["HTTP_X_FORWARDED_FOR"])){

    }elseif(!empty($_SERVER["REMOTE_ADDR"])){
          $cip = $_SERVER["REMOTE_ADDR"];
    }else{
          $cip = "";
    }
    return $cip;
}
