    public function __construct($name,$age,$gender){
        $this->setName($name);
        $this->setAge($age);
        $this->setGender($gender);
    }

    public function setName($name){
        $this->name = $name;
    }
    public function setAge($age){
        $this->age = $age;
    }

    // ... getter setter 方法

}

$peron = new Person("贺德强",18,'男');

parent::__construct();

class test{
    function __destruct(){
        echo "当对象销毁时会调用！！！";
    }

}
$a = $b = $c = new test();

$a = null;
