	}
}

class DefinedEnum extends Enum

	public function _construct($itms)
	{
		foreach($itms as $name=>$enum)
		$this->add($name,$enum);
	}
}

	}
}

$eFruits=new Enum("APPLE","ORANGE","PEACH");
echo $eFruits->APPLE.",";
echo $eFruits->ORANGE.",";
echo $eFruits->PEACH."\n";

$eBeers=new DefinedEnum("GUINESS"=>25,"MIRROR_POND"=>49);
echo $eBeers->GUINESS.",";
echo $eBeers->MIRROR_POND."\n";

$eFlags=new FlagsEnum("HAS_ADMIN","HAS_SUPER","HAS_POWER","HAS_GUEST");
echo $eFlags->HAS_ADMIN.",";
echo $eFlags->HAS_SUPER.",";
echo $eFlags->HAS_POWER.",";
echo $eFlags->HAS_GUEST."\n";
?>

这段代码我怎么看不懂啊
哪里来的$eFruits->APPLE
$eFruits->ORANGE
$eFruits->PEACH
不要见笑啊

1、你先把程序修改正确了：方法名前有下划线的方法名一律改成两个下划线的
如 _construct 改为 __construct

2、修改 __get 方法成这样
public function __get($name=null)
{
echo "读取属性 $name";
return $this->self[$name];
}
3、运行修改后的代码，你就可以知道是怎么回事了

两个下划线就都对了。
