	}
	public function eat($food){
		$this->chew($food);
		echo "<p>{$this->name}正在快速的吃{$food}！</p>";
	}

$hanMM=new Student('韩梅梅','女');
echo $hanMM->hh;

解析：

核心在于，私有性的《《《属性》》》调用时才能执行__set和__get方法。怎么执行呢？调用私有性的属性即可，但是切记调用时不能赋值哦

	const BIRTHPLACE='火星';
	private  $hh=666;
	public $studentId;
	public function __call($funcName,$agrs){
		echo "__call方法";
	}
	
	private function test($subject){
		echo "<p>{$this->name}正在考{$subject}！</p>";
	}
	public function eat($food){
		$this->chew($food);
		echo "<p>{$this->name}正在快速的吃{$food}！</p>";
	}
}
$hanMM=new Student('韩梅梅','女');
echo $hanMM->test();

解析：调用私有性的方法时才自动执行的哦

set
