Cloudflare Token Cache Clear PHP

Hi there, looking for someone who knows the Cloudflare CDN fairly well. Looking for a snippet of code written in PHP that can be inserted into a page that when run will purge the cache of several URLs cached on Cloudflare based on a URL variable on the page it is to be inserted into. The API secret token will need to be stored encrypted. This should be tested on your end and I will just insert my credentials and it will work. There is no server or Cloudflare (non-enterprise version) access granted for this project.
