php模拟post和get方法

网上发现一些post模拟方法很不靠谱，特把我用的discuz的公布出来
把post数据用数组$post_data表示出来，然后用下面的函数就可以了，非常简单，但是非常实用；
$URL是你要提交的url地址；
$referrer 是你浏览页面的上一历史页面。
如有端口号可放在$url上就行如 http://www.uusnn.com.cn：8080/getfile.php
<pre>
$post_data[0] = 'uusnn.com';
$post_data[1] = '[e-mail]';
$URL='http://www.uusnn.com.cn/getfile.php';

$referrer="";
// parsing the given URL
$URL_Info=parse_url($URL);

// Building referrer
if($referrer=="") // if not given use this script as referrer
$referrer='http://www.uusnn.com.cn';

// making string from $data
foreach($post_data as $key=>$value){
$values[]="$key=".urlencode($value);
}
$data_string=implode("&",$values);
// Find out which port is needed - if not given use standard (=80)
$content = uc_fopen($URL,'',$data_string);
echo $content;
