Answer 1

A couple of important features of the Strategy pattern as envisioned by the Gang of Four are:

1. It has no conditional statements (so leave out your switch, if, etc conditionals)
2. It has a Context participant

Most of the advice on the Strategy leaves out the Context participant. You can find five different examples of the Strategy pattern in PHP here: http://www.php5dp.com/category/design-patterns/strategy/
