title: Using SetEnv in Apache : where and how can I do that?
body: <p>I want to run locally an App I am developing. There are instructions about how to config that here : <a href="http://devcenter.heroku.com/articles/facebook#working_locally" rel="nofollow">http://devcenter.heroku.com/articles/facebook#working_locally</a> in 2).
  I am using PHP, so I will use Apache. I had already runned a PHP project thanks to WampServer, but I do not know and do not understand how it works really.</p>
  
  <p>Now I want to use SetEnv to set the env vars for my local app’s VirtualHost, as described in the link above (for FB variables). But I do not know what I have to write :</p>
  
  <pre><code>&lt;VirtualHost *:80&gt;
  DocumentRoot /Users/adam/Sites/mycoolapp-dev
  ServerName mycoolapp-dev.localhost
  SetEnv FACEBOOK_APP_ID 964173273189
  SetEnv FACEBOOK_SECRET dcd5d23d003d53cb2b68e01
  &lt;/VirtualHost&gt;
  </code></pre>
  
  <p>some file ? </p>
  
  <p>Or use the setEnv instruction in cmd.exe, somewhere ?</p>
  
  <p>I have not found further explanations, and so am completely lost.</p>
  
  <p>Thanks a lot for helping</p>
