php里面的魔术方法

name=$name;
		$this->sex=$sex;
	}
	protected function chew($food){
		echo "
{$food}已经被咀嚼完成！
";
	}
	//抽象方法
	abstract public function eat($food);
	static public function hello(){
		echo '
您好！我是来自'.self::BIRTHPLACE.'的人类
';
	}
}
class Student extends Humanity {
	const BIRTHPLACE='火星';
	private  $hh=666;
	public $studentId;
	public function __set($name,$value){
		
		 $this->$name=$value;
	}
	public function __get($name){
		
		
			return ($this->$name)*666;
		
	}
	
	public function test($subject){
		echo "
{$this->name}正在考{$subject}！
";
	}
	public function eat($food){
		$this->chew($food);
		echo "
{$this->name}正在快速的吃{$food}！
";
	}
}
$hanMM=new Student('韩梅梅','女');
echo $hanMM->hh;

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

name=$name;
		$this->sex=$sex;
	}
	protected function chew($food){
		echo "
{$food}已经被咀嚼完成！
";
	}
	//抽象方法
	abstract public function eat($food);
	static public function hello(){
		echo '
您好！我是来自'.self::BIRTHPLACE.'的人类
';
	}
}
class Student extends Humanity {
	const BIRTHPLACE='火星';
	private  $hh=666;
	public $studentId;
	public function __call($funcName,$agrs){
		echo "__call方法";
	}
	
	private function test($subject){
		echo "
{$this->name}正在考{$subject}！
";
	}
	public function eat($food){
		$this->chew($food);
		echo "
{$this->name}正在快速的吃{$food}！
";
	}
}
$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
