PHP 基础 继承
在书上发现一段代码，敲下来后发现不对。。
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><?php class Person { private $name; private $sex; private $age; function __construct($name="",$sex="男",$age=23) { $this->name=$name; $this->sex=$sex; $this->age=$age; } function say() { echo "我的名字 ".$this->name."，性别 ".$this->sex."，年龄 ".$this->age."<br>"; } function run() { echo $this->name."正在走路<br>"; } } class Student extends Person { var $school; function study() { echo $this->name."正在".$this->school."学习<br>"; } } 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."<br>"; } } $teacher1=new Teacher("张三","男",40); $teacher1->school="沈阳工学院"; $teacher1->wage=3000; $teacher1->say(); $teacher1->run(); $teacher1->teaching();?>是$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
