挖掘两个或多个对象

这样地:

class core
{

    public function __get($class)
    {
        $this->load($class);
    }

    public function load($class, $file = null, $lib = true)
    {
        if($file == null)
            $file = $class;

        if($lib == true)
            include(LIBPATH.$file.PHP);
        else
            include(SYSPATH.$file.PHP);

        $this->$class = new $class($this);
    }

}

class Child implements myStruct
{
    public function __construct($obj)
    {
         $this->obj =& $obj;
    }
}

这是像我想的那么难看,还是这个解决方案可以接受?
