PHP获取IP方法一：

<?php
echo " ";
?>
<?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 $cip;
}
echo " ";
?>
PHP获取IP方法二：
<?php echo " "; ?> <? error_reporting (E_ERROR | E_WARNING | E_PARSE); if($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." "; ?>
PHP获取IP方法三：
<?php echo " "; ?> <? $iipp = $_SERVER["REMOTE_ADDR"]; echo $iipp; echo " "; ?>
PHP获取IP方法四：
<?php echo " "; ?> <?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." "; ?>
PHP获取IP方法五：
<?php echo " "; ?> <? 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 " "; ?>
PHP获取IP方法六：
<?php echo " "; ?> <? 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 " "; ?>
