title: Feature Toggles in Symfony
body: <p>Our Symfony application is currently one application, that will soon require ability to have multiple sites point to the same Symfony core and have slightly different functionality based on which site it is currently on.</p>
  
  <p>As an example we might have a banner showing on one site but not another. Another example is a payment option that will be enabled/disabled on the different sites. Or another one is different fields on a form on the different sites.</p>
  
  <p>Has anybody had experience structuring Symfony application in this way?</p>
