php模拟post和get方法 [discuz的方法]

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.sendnet.cn:8000/getfile.php

$post_data[0] = '深达设计';
$post_data[1] = '0755-83769155';
$URL='http://www.sendnet.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.sendnet.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;

function uc_fopen($url, $limit = 0, $post = '', $cookie = '', $bysocket = FALSE, $ip = '', $timeout = 15, $block = TRUE) {

	$path = $matches['path'] ? $matches['path'].($matches['query'] ? '?'.$matches['query'] : '') : '/';
