title: Docker-Compose won't volume my php.ini file
body: <p>I'm trying to use docker-compose to volume my php.ini file so I can make changes on the fly on my local machine to see how it affects the host machine.  Unfortunately the only way I've been able to get the php.ini file into the container is directly during creation in the Dockerfile so far.</p>
  
  <p>Attached is an image of the container running fine with the current settings below.</p>

  <p>I tried following the advice here, <a href="https://stackoverflow.com/questions/39875543/cant-upate-php-ini-file-in-docker-container">can&#39;t upate php.ini file in Docker container</a>, by creating a custom.ini file and mounting it in that location.  I actually did it correctly I think because if you look at my image I attached for phpinfo(), you can see that under additional .ini files parsed my custom.ini is there at the end.  I did a test though by setting asp_tags = On instead of Off and I can't.  phpinfo() will always show it as off.  Refer to my attached image of it showing it off despite loading my config file.</p>
  
  <p>I'm not even sure if its really honoring any of the commands in there at all?</p>
