新人学习PHP问题，发现书上代码不对

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."
";		}		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();?>

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
