How to restart apache or nginx from php container?

[jibran]

As per the documentation Apache and Nginx can be restarted but php image doesn't have httpd or nginx so how do we restart apache or nginx from php container?

I'm trying to use the image on CircleCI to setup apache or nginx correctly, I should be able to restart it once the docroot is setup.
