php download.php實(shí)現(xiàn)代碼 跳轉(zhuǎn)到下載文件(response.redirect)

一直對(duì)php不太熟悉，今天需要類型asp的 response.redirect語(yǔ)句，但一直沒(méi)有很好的解決方法。下面是問(wèn)了朋友才知道的。
跳轉(zhuǎn)核心代碼實(shí)現(xiàn)。
復(fù)制代碼 代碼如下:

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



下面是國(guó)外的一篇文章說(shuō)明。

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.dbjr.com.cn/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.
