构造函数:对象初始化的时候自动调用

//构造函数
class Person{
	public $name;
	public $age;
	public $sex;
    //__construct构造函数,初始化对象
	public function __construct($name,$age,$sex){
		$this->name=$name;
		$this->age=$age;
		$this->sex=$sex;
	}
}
$person = new Person('张三丰',100,'male');
echo $person->name;//张三丰
echo $person->age;//100
echo $person->sex;//male

析构函数:对象结束的时候自动调用

class Person{
	public $name;
	public $age;
	public $sex;
	//__destruct对象结束时自动调用
	public function __destruct(){
		echo "对象结束了";
	}
}
$person = new Person('张三丰',100,'male');
//对象结束了
