如何在Codeigniter上获取用户的IP地址

Question

Use this function instead of it.

  function get_ip_address_of_user() {
   $ipaddress = array();
   if (isset($_SERVER['HTTP_CLIENT_IP']))
    $ipaddress['ip'] = $_SERVER['HTTP_CLIENT_IP'];
   else if (isset($_SERVER['HTTP_X_FORWARDED_FOR']))
    $ipaddress['ip'] = $_SERVER['HTTP_X_FORWARDED_FOR'];
   else if (isset($_SERVER['HTTP_X_FORWARDED']))
    $ipaddress['ip'] = $_SERVER['HTTP_X_FORWARDED'];
    else if (isset($_SERVER['HTTP_FORWARDED_FOR']))
    $ipaddress['ip'] = $_SERVER['HTTP_FORWARDED_FOR'];
   else if (isset($_SERVER['HTTP_FORWARDED']))
    $ipaddress['ip'] = $_SERVER['HTTP_FORWARDED'];
    else if (isset($_SERVER['REMOTE_ADDR']))
    $ipaddress['ip'] = $_SERVER['REMOTE_ADDR'];
   return $ipaddress;
  }
