PHP obtains the ip address code summary, and php obtains the ip address summary. PHP obtains ip address code Summary. php obtains ip address summary code 1: functiongetip () {static $ ip; $ ip $ _ SERVER [REMOTE_ADDR]; if (isset ($ _ SERVER [HTTP_CDN_SRC_IP]) {$ ip $ _ PHP get ip address code summary, php get ip address summary

Code 1:

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;}

Code 2:

<?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;?>

Method 3:

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

Method 4:

<?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?>

Method 5:

<?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();?>

Method 6:

<?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;?>
