设计模式PHP篇（二）————工厂模式

一个很简单的工厂模式。代码如下：

<?php

interface Person
{
	public function sex();
}

class Man implements Person
{
	public function sex()
	{
		echo "I'm a Man".PHP_EOL;
	}
}

class Women implements Person
{
	public function sex()
	{
		echo "I'm a Women".PHP_EOL;
	}
}

class Factory
{

	public static function getObject($name)
	{
		return new $name();
	}

}

$man = Factory::getObject('Man');
$man->sex();

$women = Factory::getObject('Women');
$women->sex();

/**
output results
I'm a Man
I'm a Women
*/

代码很简单，重要的是思想。
