How do I use traits in PHP 5.4

The biggest change in PHP 5.4 is the addition of traits to the object-oriented programmability.  Traits prevent code duplication by allowing multiple classes to include a collection of methods implemented as a trait.  This means multiple classes can include the same method implementations without duplicating code.

Traits improve on interfaces because they include not only the function definition, but also the implementation.  Traits can also use other traits, meaning that one trait could be a collection of others.  So, if you had traits Roll and Bounce, you could have trait Movements that used both Roll and Bounce.
