PHP 获取ip地址代码汇总

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 ;?>

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：

<?phpfunction 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：

<?phpif(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;?>
