当我尝试以这种方式向表单添加 cssrf 元素时，我的代码工作正常，突然之间：

$this->addElement('hash', 'csrf', 'Category' . time());

出现以下错误

Fatal error: Cannot return string offsets by reference in /usr/share/Zend/library/Zend/Session/Abstract.php on line 160 Stack trace: 1. {main}() /Users/myname/Sites/Zend_Projects/myproject/public/index.php:0 2.

为什么会发生这种情况以及可以做些什么呢？

从对快速入门的评论中，我觉得您也使用了一个模块并遇到了同样的问题。引用它以供快速参考。

But if you put the same same code in a module, it tries to create the session file iin the directory APPLICATION_PATH "/../data/session" which doesn't exist by default so an exception is raised.

$this->addElement('hash', 'csrf', array(
    'ignore' => true,
));

我觉得你可以使用这个插件http://codeutopia.net/blog/2008/10/16/how-to-csrf-protect-all-your-forms/

它能做什么 ？

ZF 控制器插件，可自动保护您的所有表单 - 整洁，对吧？
