Optional Value Control-flows in PHP using Traits and Magic-methods

Edd Mann demonstrates a nice trait to add OrElse functionality to a class via a trait. With it you can do things like:

[code]

$cart = $repository->findByIdOrElse(1, new ShoppingCart); $cart = $repository->findByIdOrElse(1, function () { return new ShoppingCart; });
