PHP-Traits in Symfony: Add timestamps and more to tables magically

Say you want to add a logging preprocessor to some of your classes. Either all of these classes have to inherit some kind of logger-class, or you have to copy the logging-call multiple times. Not anymore! PHP 5.4.0 introduced Traits, a wonderful way to inject code into your classes without using inheritance.

A Trait is similar to a class, but only intended to group functionality in a fine-grained and consistent way.

  • Loggable
  • Translatable
  • Sortable
  • Tree
