我正在通过JSON编码的ajax请求（表单进程）向我的PHP应用程序发送请求。成功处理字符长度为4174的后请求，并正确接收结果。在请求中添加一个附加字符会导致我的应用程序无限循环，直到Apache2发生故障。只有2个字段，一个用于3位数字，其余字段来自文本区域。
我正在使用Zend Framework来驱动我的应用程序，Apache2.2.3，PHP 5.2.8，JSON插件版本1.2.1，MySQL 5.0.77
任何人都有任何想法......
这是另一个更新:: 跟踪此问题不是json请求问题，但我正在运行的查询出现问题。我正在执行INSERT ON DUPLICATE KEY UPDATE查询，该查询会扩大查询的文本大小。我可以从命令行运行此查询查找，但是从PHP它失败了。目前正在调查此问题。有兴趣的人可以在这里查看查询..
**这是php的mysqli插件的错误，由于某种原因，db处理程序不喜欢这段代码。如果/当我有时间进行正确测试时，您会看到我的结果。**

我不知道这是否相关，但我最近使用jQuery使用$ .ajax（）方法将POST数据从文本字段提交到php脚本。然后php脚本将解析数据（XML）以获取我需要的信息。我注意到我的firephp输出错误，它无法解析POSTed表单中的XML。然后我输出了strlen（）和数据，并注意到它将它从大约7k字节切割到268（或256或者我忘记确切的数量）。这使得它成为一个不完整且无效的XML数据堆。我通过使用$ .post（）方法修复此问题。工作得很好。

您可以简单地检查字符串的长度，如果超出限制，则将其拆分。运行插入中的第一部分，然后使用第二部分对字段执行+=更新。它有点粗糙，但它可以解决这个问题。
