Single inheritance has often been the limitation for PHP. This means that a class can only inherit from one other class. Often classes share the same methods and it would be beneficial to allow reuse and prevent duplication.
In PHP 5.4 a new feature was added, known as Traits. A Trait is like a Mixin, allowing to use / mix classes into existing classes. This means code reduction and less duplication.
Example of a Trait
This trait can than be used in other classes:
Both classes can now use the Shareable trait.
The benefit is less code duplication. The drawback is, that not all used methods are visible within the source-code of the class. So before moving a method to a trait, make sure that you will actually reuse it ;)
I have been restructuring huge amounts of code over the past months and traits are helping to keep things far more organized.
In combination with __autoload its a real nice way to cleanup your code toolbox.
Happy coding Alex
