Programme one:

你可以在B页面的链接添加$_GET['xx'],只要从A页面带参数跳转到B页面的话,那B页面的链接就必然会带上刚刚的$_GET['xx']参数.这是点击链接跳转到C页面也就可以接受刚刚从A->B的参数了.

Scenario Two:

在B页面使用SESSION或者COOKIE存储$_GET['xx']参数,在C页面通过读取SESSION或者COOKIE来获取参数.

When you generate the HTML for page B, you can add the arguments passed in a to the URL, which you can simply do:

  
   ">Page C

Another way is to consider the existence of variables in the session.

$param = parse_url( $_SERVER['HTTP_REFERER'] );list($key, $val) = explode('=', $param['query']);

You can consider using the session, according to your needs, the page opened through hyperlinks belong to the same session ...

The feeling describes a scenario, whether it can describe the requirements, that is, why.

Yes, you can use the session, or you can use the URL behind the stitching method
