其之所以出现多个->，让人一看还真的蒙了，特别是给你看一段代码片段，蒙了，于是经过推敲后，得出如下代码：
<?php class user {   public $name;   function user() {     $this -> name = "莫莫";   } } ; class sessionobj {   public $user;   public function sessionobj() {     $this -> user = new user();   } } ; class getSessionName {   public $session;   public function getSessionName() {     $this -> session = new sessionobj();   }   public function getNameBySession() {     return $this -> session -> user -> name;   } } //实例化这个最后的类并输出 $nickName = new getSessionName(); echo $nickName -> getNameBySession(); ?> ]]> http://jackxiang.com/post/5614/#blogcomment63809 hxngb1uf <ufxs91@chong-mail.net> Sun, 30 Sep 2012 18:42:58 +0000 http://jackxiang.com/post/5614/#blogcomment63809
