title: Setting up heroku with PHP-FPM
body: <p>I have custom environment variables being set in the php.ini file. I want to override those values in the <code>user.ini</code> (to show different things based on this env on heroku) or <code>fpm_custom.conf</code> file but I cant seem to get the combination / syntax right.</p>
  
  <p><strong>In the <code>php.ini</code> file</strong></p>
  
  <ul>
  <li>env_mode = "Production"</li>
  </ul>
  
  <p><strong>In the <code>user.ini</code> file</strong></p>
  
  <p><code>env_mode = "Development"</code></p>
  
  <p><strong>In the Procfile</strong></p>
  
  <p><code>web: vendor/bin/heroku-php-apache2 -F fpm_custom.conf www/</code></p>
  
  <p><strong>In the <code>fpm_custom.conf</code> file</strong></p>
  
  <p><em>??? Here's where I want to set env_more</em></p>
  
  <p>I've tried </p>
  
  <ul>
  <li><code>ENV_MODE = "Development"</code></li>
  <li><code>php_value[ENV_MODE]=Development</code></li>
  <li><code>php_value ENV_MODE Development</code></li>
  </ul>
  
  <p>Any help would be great!
  Thanks</p>
