来源:互联网

本篇文章主要介绍php 获取ip地址的六种方法,感兴趣的朋友参考下,希望对大家有所帮助。

代码一:

function getip() {  static $ip = '';  $ip = $_SERVER['REMOTE_ADDR'];  if(isset($_SERVER['HTTP_CDN_SRC_IP'])) {    $ip = $_SERVER['HTTP_CDN_SRC_IP'];  } elseif (isset($_SERVER['HTTP_CLIENT_IP']) && preg_match('/^([0-9]{1,3}\.){3}[0-9]{1,3}$/', $_SERVER['HTTP_CLIENT_IP'])) {    $ip = $_SERVER['HTTP_CLIENT_IP'];  } elseif(isset($_SERVER['HTTP_X_FORWARDED_FOR']) AND preg_match_all('#\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}#s', $_SERVER['HTTP_X_FORWARDED_FOR'], $matches)) {    foreach ($matches[0] AS $xip) {      if (!preg_match('#^(10|172\.16|192\.168)\.#', $xip)) {        $ip = $xip;        break;      }    }  }  return $ip;}

代码二:

<?phperror_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 ;?>

<?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:

<?phpfunction get_real_ip(){$ip=false;if(!empty($_SERVER["HTTP_CLIENT_IP"])){ $ip = $_SERVER["HTTP_CLIENT_IP"];}if (!empty($_SERVER[&#39;HTTP_X_FORWARDED_FOR&#39;])){ $ips = explode (", ", $_SERVER[&#39;HTTP_X_FORWARDED_FOR&#39;]); if($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 get_real_ip();?>

方法六:

<?phpif(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;?>
