在书上发现一段代码,敲下来后发现不对。。

sex=$sex;			$this->age=$age;		}		function say()		{			echo "我的名字  ".$this->name.",性别  ".$this->sex.",年龄  ".$this->age."
"; } function run() { echo $this->name."正在走路
"; } } class Student extends Person { var $school; function study() { echo $this->name."正在".$this->school."学习
"; } } class Teacher extends Student { var $wage; function teaching() { echo $this->sex."正在".$this->school."教学,每个月工资为".$this->wage."
"; } } $teacher1=new Teacher("张三","男",40); $teacher1->school="沈阳工学院"; $teacher1->wage=3000; $teacher1->say(); $teacher1->run(); $teacher1->teaching();?>
登录后复制

这里Teacher类中的teaching方法或不去不到$this->name。。书上却写可以获取的到,是我哪里写错了吗?


回复讨论(解决方案)

是$this->sex获取不到数据。

额。。。。我马虎了,上面变量定义的是private属性,当然获取不到。。。

同样菜的鸟飞过.........

你没错,书上也没错!
只不过是错误检查的级别不同而已

error_reporting = E_ALL ^ E_NOTICE
就一致了

private $name;
private $sex;
private $age;
private改成public
