SimasToleikis' Blog: New to PHP 5.4: Traits

Simas Toleikis has a new post to his blog looking at a feature that'll be included in PHP 5.4 - something developers have been wanting for a long time - traits.

As a long-time internals.php mailing list reader I am going to tell you a small secret - the first alpha release for PHP 5.4 should be just around the corner. This release is packed with some welcome new language features, usual bug fixes followed by some performance and memory management improvements. One of the noteworthy language additions are Traits - a brand new horizontal code reuse mechanism.

He explains traits as a better way to do the "kind-of" inheritance that PHP does now with parent and child classes, making it easier to reuse functionality from classes even though they don't share the same parent. With the "use" keyword (not to be confused with the "use" keyword in namespaces) you can include common functionality into class methods and even accommodate for naming conflicts and requirements.
