PHP获取IP的方法有许多种，我们今天向大家总结了六种方法，希望通过对这六种方法的学习，能够加深我们对PHP语言的进一步了解，巩固我们所掌握的知识。

PHP获取IP方法一：

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

PHP获取IP方法二：

<?php echo "<br>";  ?>  <? 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                                             {                                                       $ip = "Unknown";                                         }                                                echo "你的IP地址是:".$ip."<br>";                              ?>

PHP获取IP方法三：

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

PHP获取IP方法四：

<?php echo "<br>";  ?>  <?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."<br>";  ?>

PHP获取IP方法五：

<?php echo "<br>";  ?>  <? 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();  echo "<br>";  ?>

PHP获取IP方法六：

<?php echo "<br>";  ?>  <? 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;  echo "<br>";  ?>
