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

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:
// process form
// ...
// redirect to results page
header('Status: 303 See Other' );
header('Location: http://www.jb51.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.
