    curl_close($socket); 
   ?>

Answer 1

Use session_start() function .

Answer 2

Since you're referring to a cookies.txt file without any reference to a folder my first guess would be that you're trying to write to a file in a folder that isn't writable. So first check if you actually find a cookies.txt file and if it contains the session cookie(s) you would expect.

Answer 3

I would probably move that code into a function. After successful login, you now have the session associated with the cookie you have in your cookie.txt file. On subsequent requests, just keep using that cookie file and you should have a valid session on that site.
