php curl to page and store $_GET variable in a cookie before page redirects

Question

I am using php curl to view this webpage remotely http://agentnet.propertyguru.com.sg/ex_login?w=1&redirect=/ex_home

The page redirects to another page /distil_identify_cookie.html?uid=... before redirecting back to the initial login page

I have set the following in my curl script

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, FALSE);

This did not stop the page from redirecting.

Can anyone advise how I can store this $_GET variable "uid" in a cookie before the page redirects?

Add:

After executing the curl statements ($response = curl_exec($ch);), $response is as per below

HTTP/1.1 200 OK Server: nginx Date: Sun, 06 Jul 2014 08:47:32 GMT Content-Type: text/html 
Transfer-Encoding: chunked Connection: keep-alive Vary: Accept-Encoding

I cannot find anything in the header stating the uid value...

You can set both CURLOPT_FOLLOWLOCATION and CURLOPT_HEADER to TRUE. This way, in the final result you`ll have the headers for all redirects that happen during your request. Then, you can parse the headers to get the info you need.
