php 获得ip地址

admin 11月 11, 2020 0

方法一：

<?php
function (){
  if(!empty($_SERVER["HTTP_CLIENT_IP"])){
    $cip = $_SERVER["HTTP_CLIENT_IP"];
  }elseif(!empty($_SERVER["HTTP_X_FORWARDED_FOR"])){
    $cip = $_SERVER["HTTP_X_FORWARDED_FOR"];
  }elseif(!empty($_SERVER["REMOTE_ADDR"])){
    $cip = $_SERVER["REMOTE_ADDR"];
  }else{
    $cip = "无法获取！";
  }
  return $cip;
}
echo GetIP();
?>

方法二：

<?php
error_reporting (E_ERROR | E_WARNING | E_PARSE);
if($HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"]){
  $ip = $HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"];
}elseif($HTTP_SERVER_VARS["HTTP_CLIENT_IP"]){
  $ip = $HTTP_SERVER_VARS["HTTP_CLIENT_IP"];
}elseif ($HTTP_SERVER_VARS["REMOTE_ADDR"]){
  $ip = $HTTP_SERVER_VARS["REMOTE_ADDR"];
}elseif (getenv("HTTP_X_FORWARDED_FOR")){
  $ip = getenv("HTTP_X_FORWARDED_FOR");
}elseif (getenv("HTTP_CLIENT_IP")){
  $ip = getenv("HTTP_CLIENT_IP");
}elseif (getenv("REMOTE_ADDR")){
  $ip = getenv("REMOTE_ADDR");
}else{
  $ip = "Unknown";
}
echo $ip;
?>

方法三：

<?php
  $iipp = $_SERVER["REMOTE_ADDR"];
  echo $iipp ;
?>

方法四：

<?php
  $user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];
  $user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];
  echo $user_IP
?>

方法五：

<?php
function get_real_ip()
{
  $ip=false;
  if(!empty($_SERVER["HTTP_CLIENT_IP"])){
    $ip = $_SERVER["HTTP_CLIENT_IP"];
  }
  if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){
    $ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);
    if($ip){
       array_unshift($ips, $ip); $ip = FALSE;
    }
    for($i = 0; $i < count($ips); $i++){
       if (!eregi ("^(10|172.16|192.168).", $ips[$i])){
          $ip = $ips[$i];
        break;
     }
    }
  }
  return($ip ? $ip : $_SERVER['REMOTE_ADDR']);
}
echo get_real_ip();
?>

方法六：

<?php
if(getenv('HTTP_CLIENT_IP')){
  $onlineip = getenv('HTTP_CLIENT_IP');
}elseif(getenv('HTTP_X_FORWARDED_FOR')){
  $onlineip = getenv('HTTP_X_FORWARDED_FOR');
}elseif(getenv('REMOTE_ADDR')){
  $onlineip = getenv('REMOTE_ADDR');
}else{
  $onlineip = $HTTP_SERVER_VARS['REMOTE_ADDR'];
}
echo $onlineip;
?>
