php如何使用_call实现多继承（代码示例）

class One{
    function method_1(){
        echo &#39;11<br/>&#39;;
    }
    function method_2(){
        echo &#39;22<br/>&#39;;
    }

}
class Two{
    function method_3(){
        echo &#39;33<br/>&#39;;
    }
    function method_4(){
        echo &#39;44<br/>&#39;;
    }
}
class StaticDemo{

    protected $Class = array();

    public function __construct(array $class = array()){
        $this->Class = $class;
    }

    public function __call($name, $arguments)
    {
        // TODO: Implement __call() method.
        foreach ($this->Class as $v){
            if (is_callable(array($v, $name))) {
                //call_user_func_array在上篇文章中已作出理解
                return call_user_func_array(array($v, $name), $arguments);
            }
        }
        return call_user_func_array(array($this, $name), $arguments);
    }

}

$obj = new StaticDemo(array(new One(), new Two()));
$obj->method_1();
$obj->method_3();
