Cron job has a different output then running a script in the browser

I'm running the following code on my server, the script works fine in the browser but when i try it in a cronjob or through shell logged in as root i get a totally different output.

output through the browser:

• logs in and gets the page i want

output through shell / cron:

• doesn't seem to login, but gets the contents of the page redirecting me back to the login page.

i'm using red hat linux 5

Firstly check the output of the command if you execute it as your web user (typically www-data) with

su www-data /usr/bin/php /var/www/vhosts/domain.co.uk/httpdocs/store/curl_test.php

If that works then this is a permissions error so ensure the user you're running the cron job as can write to the file "/var/www/vhosts/domain.co.uk/httpdocs/store/cookie".
