看高老师的视频 __set魔术方法是可以加private属性的
我加了就出现以下错误：Warning: The magic method __set() must have public visibility and cannot be static in D:\wamp\www\index.php on line 15
王五

代码如下：


class demo {

private $name;
private $age;
private $sex;

function __construct($name,$age,$sex) {
$this->name=$name;
$this->age=$age;
$this->sex=$sex;
}

private function __set($proname,$provalue) {
$this->$proname=$provalue;
}

function say() {
echo $this->name;
}

}

$p1=new demo('张三',38,'男');

$p1->name="王五";

$p1->say();

?>

是不是php版本问题，我用的是php5.3.3
