Question

I want to make an application that will be receiving get requests and respond with xml.
Here’s the scenario:

User comes to site_a.com?site.phpid=abc, from there I have to make a GET request to site_b.com/checker.php?id=abc.

How to make a GET request without user leaving the page?

Inside checker.php I have to respond with xml depending on that id

if(isset($_GET['id'])){
  if($_GET['id']=='abc'){
    // respond with xml
 }
}

and then is site.php I have to receive that xml.

Thanks!

Answer 1

The easist way, you could use file_get_contents:

//site.php?id=abc
$xmlResponse = file_get_contents("site_b.com/checker.php?id=abc");

But make sure allow_url_fopen can be true.
