本文标签：php,跳转,下载文件 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 。 Hey Chris: On Wed, Jan 26, 2005 at 12:28:19PM -0500, csnyder wrote: > > <?php > // process form > ... > // redirect to results page > header( HTTP/1.1 303 See Other ); > header( Location: result.html ); > exit( Form submitted, <a href="result.html">continue</a>. ); > ?> 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.jb51.net/result.html); ?> 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. Later, --Dan |
