php如何根据url参数缓存到memcache?

<?php<br />
$file=file('link.txt');<br />
$max=count($file)-1;<br />
for($i=0;$i<5;$i++){<br />
	$index=mt_rand(0,$max);<br />
	$temp= "".trim($file["$index"])."";<br />
<br />
}<br />
$link = memcache_init();<br />
$minute_now = date('i',time());//取当前的分钟数<br />
$key = 'rate'.$minute_now;<br />
if(memcache_get($link,$key) == null)<br />
{<br />
        memcache_set($link, $key, $temp, 0, 20);//set<br />
        //注意此处的20是缓存过期时间,60秒为1分钟<br />
     <br />
}<br />
$re = memcache_get($link,$key,$temp);<br />
var_dump($re);<br />
if($re>RATEMAX)<br />
{<br />
<br />
}else{<br />
        memcache_increment($link,$key);<br />
}<br />
<br />
<br />
 ?>

没有缓存之前是每次刷新都是变的
缓存之后
演示地址http://niaochen006.sinaapp.com/zq.php
缓存时间 20秒变一次

我想要实现的是

http://niaochen006.sinaapp.com/zq.php?=*****

每个URL参数不同就缓存不同的页面
如何实现呢?


------解决方案--------------------
改造一下 $key 
你现在的
$key = 'rate'.$minute_now;
是与时间相联系的

改成与 $url 相关的就是了
