PHP代码-/ip/index.php-放在自己的网站里

<?php
function getip(){

	} elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
		$ip = $_SERVER['REMOTE_ADDR'];
	}
	return preg_match ( '/[\d\.]{7,15}/', $ip, $matches ) ? $matches [0] : '127.0.0.1';
}
$ip = getip();
$ipjson = file_get_contents('http://ip.taobao.com/service/getIpInfo.php?ip=' . $ip);
