我看lamp教程上面没报警告，我这个怎么报警告了

还有这么用到底对不对？

源码：

class Person {
		private $name;
		private $age;
		private $sex;
	
		function __construct($name="", $age=0, $sex="男"){
			$this->name=$name;
			$this->age=$age;
			$this->sex=$sex;
		}

		private function __get($proName){
			if($proName=="age"){
				if($this->age>40)
					return $this->age-10;
			}

			return $this->$proName;
		}

		private function __set($proName, $proValue){
			if($proName=="age"){
				if($proValue > 100 || $proValue < 0)
					return;
			}

			$this->$proName=$proValue;
		}
			

		function say(){
			echo "我的名子：{$this->name}，我的年龄：{$this->age}，我的性别：{$this->sex}。<br>";
		}

		function run(){
			$this->left();
			$this->left();
			$this->right();
			$this->right();
			$this->gogo();
			$this->gogo();
			$this->gogo();
		}

		private function left(){
			echo "LLLLLLLLLLLLL<br>";
		}
		private function right(){
			echo "RRRRRRRRRRRRRR<br>";
		}

		private function gogo(){
			echo "GGGGGGGGGGGGGGGGG<br>";	
		}

		private function __isset($proName){
			if($proName=="age")
				return false;
			return isset($this->$proName);
		}

		private function __unset($proName){
			unset($this->$proName);
		}

		function eat(){
		
		}

		function __destruct(){
			echo $this->name."再见！<br>";
		}
	}



$p1=new Person("zhangsan", 80, "女");
$p2=new Person("lisi", 25);
$p3=new Person("wangwu");

unset($p1->name);


if(isset($p1->name)){
	echo "存在<br>";
}else{
	echo "没有这个成员 <br>";
}

哪个误人子弟的教程？

不会是你看漏了写着“这是错误的例子”吧？

[q344617263]

魔术方法__get() 必须声明为public 并且不能是静态的

[spg120]

绝对没看错，lamp兄弟连的教程

正常啊, 只是个warning,他们把错误提示关了....

给个链接, 让我们去嘲笑嘲笑.... :)

这节讲的是面向对象封装，说的是
有些东西封装起来就能成为一个整体这个意思我自学没多长时间，我知道只要把private改成public就对了，但以后再遇到这种情况该怎么办呢？哪种是对啊？

[yuanjiulin]

我运行怎么没报错呀？

[ImN1]

手册上面写的很清楚，魔术方法都要public

楼上没报错估计是ini里面把错误报告的选项关闭了

哄哄，楼主这个例子俺看过，那本叫《细说php》来着，果然误人子弟的例子。

也不要那样说。一本书有一点bug也没有什么。总得来说还是可以的。我的了多部php的书。也没有那本比它好很多。

别人能运行正常，那就是自我的问题，这也是一种经验的积累。偶尔出现一些问题可以加深记忆，太多了就怀疑你能力了，
