示例1: array
<?php
namespace DesignPatterns\Strategy;
/**
* strategy pattern
*
* Terminology:
* - Context
* - Strategy
* - Concrete Strategy
*
* Purpose:
* to separate strategies and to enable fast switching between them.
* also this pattern is a good alternative to inheritance (instead of having an abstract class that is extended)
*
* Examples:
* - sorting a list of objects, one strategy by date, the other by id
* - simplify unit testing: e.g. switching between file and in-memory storage
*
