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['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;?>
