PHP面向对象深入理解之四(设计模式-工厂模式)

适用于创建相同类型的模型类能使代码更加健壮
举个栗子：车Car —> 奥迪，福特，宝马… 我们要造一辆

重要的是我们不需要引入所有相关类，我们只需要引入一个工厂类即可

interface Car
{
    public function makeCircle();
    public function makeBody();
    public function makeEngine();
    public function makeDecoration();
}
class Audi
{
    public function makeCircle()
    {
        echo 'make Audi Circle';
    }
    public function makeBody()
    {
        echo 'make Audi Body';
    }
    public function makeEngine()
