php里面的魔术方法__魔术方法名__():__set __get __call

 public $name; public $sex; public $iq=10; protected $money; protected $dna; const BIRTHPLACE='地球'; static public $counter=0;//静态属性，它是公共的资源和具体的实例没有关系 //构造函数 public function __construct($name,$sex){ self::$counter++; $this->name=$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; 

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

 public $name; public $sex; public $iq=10; protected $money; protected $dna; const BIRTHPLACE='地球'; static public $counter=0;//静态属性，它是公共的资源和具体的实例没有关系 //构造函数 public function __construct($name,$sex){ self::$counter++; $this->name=$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
