php 获取 ip 地址 函数:
function getIP () //取IP函数
{
     global $_SERVER;
if (getenv(‘HTTP_CLIENT_IP‘)) {
$ip = getenv(‘HTTP_CLIENT_IP‘);
} else if (getenv(‘HTTP_X_FORWARDED_FOR‘)) {
$ip = getenv(‘HTTP_X_FORWARDED_FOR‘);
} else if (getenv(‘REMOTE_ADDR‘)) {
$ip = getenv(‘REMOTE_ADDR‘);
} else {
$ip = $_SERVER[‘REMOTE_ADDR‘];
}
return $ip;
}

扩展：

<?php class clientGetObj
