PHP 面向接口编程示例

1、定义一个接口！示例如下：//定义接口interface PersonInterface{ public function say($name); public function walk($name,$parm);}

3、Man类实现此接口：//男人class Man implements PersonInterface{ pu芟鲠阻缒blic function say($name){ echo "My name is <span style=\"color:red;\">{$name}</span>.and I am a man!!"; } public function walk($name,$parm){ echo "{$name} walk {$parm} meters away."; }}

5、测试：//type类型$type='man';//名字$name='Tom';//获取实例对象$person= PerFact::getInstance($type);//调用方法$person->say($name);
