【问题描述】：
我从在 Flash Builder 4 中创建的 Flash 应用返回了一个数组。
我有一个服务设置，可以成功查询并从数据库中取回数据，但是更新脚本正在生成未定义属性错误。
我仍在学习 PHP 和 Flash Builder，但不完全理解 $this-> 命令的作用。
如果有人能指出这个脚本哪里出了问题，它基本上只是由 Flash Builder 生成的，不是我自己开发的，我会很感激吗？
另外，如果有人可以向我解释 $this-> 那也太棒了？
我以前见过它们，但后来我看到脚本做同样的事情但不使用它们，那么这是一种旧的做事方式吗？
非常感谢任何人提供的任何意见。
更新了完整的 PHP 代码。
产生的错误。

-
您能否添加确切的错误消息以及它们出现在哪些行中？
-
尽快了解您编码的语言。巧合的编程比正确的编程要付出更多的努力。
