Purge the <a href="http://nginx.org" rel="nofollow ugc">Nginx</a> cache (FastCGI, Proxy, uWSGI) automatically when content changes or manually within WordPress.
Requirements:
<ul>
<li>The <a href="https://codex.wordpress.org/Filesystem_API" rel="nofollow ugc">Filesystem API</a> needs to function without asking for credentials.</li>
<li>Nginx and PHP need to run under the same user, or PHP’s user needs write access to Nginx’s cache path.</li>
</ul>

purge_zone() need to check that rmdir() can purge all cache files or not 

Not so good

Perfect

Awesome
