Doctrine Listener versus Subscriber

Question

I\'m working in the Symfony2 framework and wondering when would one use a Doctrine subscriber versus a listener. Doctrine\'s documentation for listeners is very clear, howe

Answer 1

Both allow you to execute something on a particular event pre / post persist etc.

However listeners only allow you to execute behaviours encapsulated within your Entity. So an example might be updating a "date_edited" timestamp.

If you need to move outside the context of your Entity, then you'll need a subscriber. A good example might be for calling an external API, or if you need to use / inspect data not directly related to your Entity.
