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;
}
下面是国外的一篇文章说明。

Good point. But some feedback here. The optimail syntax is:
<?php
// process form
// ...
// redirect to results page
header(Status: 303 See Other );
header(Location: //
?>
Heres 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 doesnt 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 dont want any output after the location header.
