A Doctrine entity listener template for your Symfony project

Published on 2021-04-26 • Modified on 2021-04-26

This is a Doctrine entity listener empty template for Symfony that you can copy-paste in your projects. I wanted to have it here on my blog so I don't have to search for it in my other projects. I'll update as soon as it needs to.
