在set和get方法中使用的是$this->$name，我一看就蒙了，平时给属性赋值$this->name='sss'; 求详细介绍和解释！！！！！
后者是变量
前者是变量的变量
$name=aaa;
$this->$name 等於 $this->aaa;
$this->aaa是??量
class a{ private $name; $this->name; private $$name; $this->$name;}我明白了，发完帖子之后想通了，其实就是传递进来一个变量，实际上我要给变量的变量赋值。
<?php class classname{ private $attribute; function __get($name) { echo "__get"."<br />"; return $this->$name."<br/>"; } function __set($name,$value) { echo "__set"."<br />"; $this->$name=$value; } } $a = new classname; $a->attribute = 90; echo $a->attribute; ?>
