PHP代码：
<br>
if (getenv('HTTP_CLIENT_IP')) {<br>
$ip = getenv('HTTP_CLIENT_IP');<br>
}elseif (getenv('HTTP_X_FORWARDED_FOR')) {<br>
$ip = getenv('HTTP_X_FORWARDED_FOR');<br>
}elseif (getenv('HTTP_X_FORWARDED')) {<br>
$ip = getenv('HTTP_X_FORWARDED');<br>
}elseif (getenv('HTTP_FORWARDED_FOR')) {<br>
$ip = getenv('HTTP_FORWARDED_FOR');<br>
}elseif (getenv('HTTP_FORWARDED')) {<br>
$ip = getenv('HTTP_FORWARDED');<br>
}else {<br>
$ip = $_SERVER['REMOTE_ADDR'];<br>
}<br>
echo $ip;<br>
得到的结果：<br>
<?php
if (getenv('HTTP_CLIENT_IP')) {
$ip = getenv('HTTP_CLIENT_IP');
}elseif (getenv('HTTP_X_FORWARDED_FOR')) {
$ip = getenv('HTTP_X_FORWARDED_FOR');
}elseif (getenv('HTTP_X_FORWARDED')) {
$ip = getenv('HTTP_X_FORWARDED');
}elseif (getenv('HTTP_FORWARDED_FOR')) {
$ip = getenv('HTTP_FORWARDED_FOR');
}elseif (getenv('HTTP_FORWARDED')) {
$ip = getenv('HTTP_FORWARDED');
}else {
$ip = $_SERVER['REMOTE_ADDR'];
}
echo $ip;
?>
