php可以在没有用户请求的情况下在服务器端运行代码吗？

Question

Server 1 Pings/Request URL http://website.com/page.php?code=NeedThat

Server 2 "page.php" grabs "NeedThat" and execute img src or JavaScript on server side

Image Code on page.php

Thanks a lot forr the help got it!

Answer 1

Executing gotit.php is easy. You just use curl or (if allowed) file_get_contents to download the image src. For the JavaScript, you need to figure out what network requests that causes, then do them manually.

EDIT: If gotit needs to keep outputting that image, then you can have page.php parse the HTML, then do its own request to the resulting src (which will be website.com/sale.php...).

Answer 2

If you just need to run another script, file_get_contents can be filled out with the correct parameters and have the return value saved as such:

$result = file_get_contents('http://location.com/page.php?code=' . $code);

More advanced solutions can be crafter with something like curl, but for a simple request, file_get_contents should suffice.
