PHP使用方法重载实现动态创建属性的get和set方法

class Car {    public $name = 'car';        public function __clone() {        $obj = new Car();        $obj->name = $this->name;    }}$a = new Car();$a->name = 'new car';$a->gettime = function(){echo time();};

但是在调用的时候，除了错，我的调用方式是：$a->gettime(); 报的错是：Fatal error: Call to undefined method Car::gettime()，没有定义，明明定义了，郁闷死了。

Google去……

搜到如下可以正确执行的方式：

1.

class Foo{    public function __call($method, $args)    {        if (isset($this->$method)) {            $func = $this->$method;            $func($args);        }    }}$foo = new Foo();$foo->bar = function () { echo "Hello, this function is added at runtime"; };$foo->bar();

2.

你添加的方法没问题，只是调用错了，不能直接 $me->doSomething();

应该为： 

$func = $me->doSomething;

$func();

或者：

call_user_func($me->doSomething);

    $obj = new StdClass();    $obj->func = function(){        echo "hello";    };    //$obj->func(); // doesn't work! php tries to match an instance method called "func" that is not defined in the original class' signature    // you have to do this instead:    $func = $obj->func;    $func();    // or:    call_user_func($obj->func);

这里还遇到另一个问题
