class Person { /**

APO的主要思路 (__call魔术方法:调用一个没有的方法时执行)
interface Monitor{
public function __construct($class);
public function __call($name, $arguments);
} abstract class Event{
public abstract function before();
public abstract function after();
} class MonitorBase implements Monitor{
private $classes = null;
public function __construct($class){
$this->classes=$class; }
public function __call($name, $arguments){
echo "前置输出";
echo $name; call_user_func(array($this->classes,$name),$arguments);
echo "后置输出";
}
}
测试 :
$p = new MonitorBase(new Person());
$p->say("888",'666',array(1,2,3,65,4)); $d = new MonitorBase(new Dog());
$d->say();
结果:
最后:细心的读者可能注意到 抽象类Event 没有用到
这个其实可以让 Person 和Dog 继承然后重写 before()和after(),这样每一个类都有自己的前置和后置通知了...
