一直对php不太熟悉，今天需要类型asp的 response.redirect语句，但一直没有很好的解决方法。下面是问了朋友才知道的。 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: http://www.ruanchen.com/');
?>
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.
