php中的__get（）函数行为

class testme
{
    public $var1;
    /*function __construct()
    {
        echo\'<br/> Constructor called\';
    }*/
      public function __set($name, $value)
    {
        echo\'<br/> You are in sssset function\';
    }
    public function __call($method,$arg)
    {
        echo \'<br/> call method\';
    }
    public function __get($name)
    {
        echo\'<br/> You are in get function\';
    }
    public function __isset($name)
    {
        echo\'<br/> You are in isset function\';
    }
    public function __unset($name)
    {
        echo\'<br/> You are in unset function\';
    }   
       function __destruct() {
       print \"<br/>Destroying \" . $this->name . \"\\n\";
   }
}
$obj = new testme;
$obj->var1=5;
