Why would you manipulate nginx cache files from php directly (or even if you do so why not run the nginx and phpfpm under same user then)? 

If you want to purge the request (only valid reason which comes to my mind) you should configure fastcgi_cache_purge ( http://nginx.org/en/docs/http/ngx_http_fastcgi_module.html#fastcgi_cache_purge ).  The drawback is that's only for the commercial version.

As an alternative you could use a third party module http://labs.frickle.com/nginx_ngx_cache_purge/ 
I'm not 100% sure about the compability with the newest nginx releases but you can contact the author about that (he is also in this list).
