php download.php实现代码 跳转到下载文件(response.redirect)

答案：跳转核心代码实现。
复制代码 代码如下:

if (isset($link)) 
                { 
                    Header("HTTP/1.1 303 See Other"); 
                    Header("Location: $link"); 
                    exit; 
                }

Good point. But some feedback here. The optimail syntax is: 
<?php 
// process form 
// ... 
// redirect to results page 
header('Status: 303 See Other' ); 
header('Location: http://www.zhaoxi.net/result.html'); 
?> 
Here's why... 
Using "Status:" in the header is better because the resulting headers from 
Apache are more correct: 
HTTP/1.1 303 See Other 
instead of 
HTTP/1.1 303 
Additionally, one doesn't really know which version of HTTP is being used, 
so why potentially cause problems by trying to guess. 
The specs say location headers must have a complete URI in them, not just 
the path. 
Lastly, you don't want any output after the location header.
