如何知道用户从哪个URL重定向到php中我们网站的页面

Question

I have written a webservice client connected to a bank address. After the user is being sent to the bank's website and completes the from, then automatically is being redirected to the page named callback.php

Now, I want to know that from which address the user is being redirected to callback page?! Is there a way to know it through PHP and of course if possible in codeigniter?!

Answer 1

You should be able to access the referring location (if the user's browser has sent it, that is), with the following variable $_SERVER['HTTP_REFERER']

This should be accessible to you regardless of framework.
