建立一个用户的类,该类中有“姓名”、“学号”、“年龄”、“联系电话”四个私有属性,要求通过构造函数给属性“姓名”赋值,其他属性也通过方法来进行赋值和访问。打印出用户“张三”、“200440132”“21”、“63886666”的信息。
class Message
{
private $name;
private $num;
private $age;
private $tel;
function __construct($name,$num,$age,$tel)
{
$this->name=$name;
$this->num=$num;
$this->age=$age;
$this->tel=$tel;
}
