在很我的时候我们需要得到用户的真实IP地址,例如,日志记录,地理定位,将用户信息,网站数据分析等,其实获取IP地址很简单$_SERVER[\'REMOTE_ADDR\']就可以了。下面我们就来给大家汇总一下常用的几种获取IP地址的方法。

//方法1:

$ip = $_SERVER["REMOTE_ADDR"];
echo $ip;
Copy after login

//方法2:

代码如下:

$user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];
$user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];
echo $user_IP;
Copy after login


//方法3:

function getRealIp()
{
  $ip=false;
  if(!empty($_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[&#39;REMOTE_ADDR&#39;]);
}
echo getRealIp();
Copy after login

//方法4:

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 ;
Copy after login

//方法5:

if(getenv(&#39;HTTP_CLIENT_IP&#39;)) {
  $onlineip = getenv(&#39;HTTP_CLIENT_IP&#39;);
} elseif(getenv(&#39;HTTP_X_FORWARDED_FOR&#39;)) {
  $onlineip = getenv(&#39;HTTP_X_FORWARDED_FOR&#39;);
} elseif(getenv(&#39;REMOTE_ADDR&#39;)) {
  $onlineip = getenv(&#39;REMOTE_ADDR&#39;);
} else {
  $onlineip = $HTTP_SERVER_VARS[&#39;REMOTE_ADDR&#39;];
}
echo $onlineip;
Copy after login

//方法6:

print "您的IP地址是:";


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!";
}
print $cip;
Copy after login
