【问题描述】：
我正在阅读一本书（Zend Framework, A Beginners Guide），这本书中有很多错误，但幸运的是，到目前为止，除了这个之外，我已经解决了所有错误。
我收到以下错误：
致命错误：未定义的类常量 “无效”在 C:\xampp\htdocs\projects\zend\square\library\Square\Form\ItemCreate.php 第 40 行
代码在这里：

错误来自 Zend_Validate_Regex::INVALID，但我似乎找不到任何网站可以解释为什么会发生此错误。
谁能帮我解决这个问题？这是正常的还是我在这里遗漏了什么？
我花了几个小时试图自己解决这个问题并阅读了文档，但显然我遗漏了一些东西......我认为这可能是因为我需要实例化 Zend_Validate_Regex，但是当我这样做时我只是得到一个空白页，所以我认为我不应该这样做。
任何帮助将不胜感激！
