Solution 1:

You can add $ _ GET ['xx'] At the link of page B. If you want to jump from page A to page B with parameters, then the link to page B will inevitably include the $ _ GET ['xx'] parameter. this is when you click the link to jump to the C page, you can accept the parameters just from A-> B.

Solution 2:

Use SESSION or COOKIE to store $ _ GET ['xx'] parameters on page B, and read SESSION or COOKIE on Page C to obtain parameters.

When generating the HTML of page B, you can add the parameters passed by A to the URL. in simple words, you can perform the following operations:

  ">Page C

Another way is to store the variable in the session.

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

You can consider using session. Based on your needs, the page opened through a hyperlink belongs to the same session...

I feel like it is a solution. Can you describe the requirements? That is to say, why.

Yes. You can use session or url-based stitching.
