Nginx includes a FastCGI module which has directives for caching dynamic content that are served from the PHP backend. Setting this up removes the need for additional page caching solutions like reverse proxies (think Varnish) or application specific plugins. Content can also be excluded from caching based on the request method, URL, cookies, or any other server variable.
