php - json post 请求大小限制(现在是一个经过验证的 php-mysqli 错误)

Question

我正在通过 JSON 编码的 ajax 请求(表单处理)向我的 PHP 应用程序发送请求。成功处理了一个字符长度为4174的post-request，并正确接收到结果。向请求添加一个额外的字符会导致我的应用程序无限循环，直到 Apache2 出现段错误。只有 2 个字段，一个用于 3 位数的 ID，其余的是来自文本区域的文本。

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

谁有什么想法...

这是另一个更新:: 跟踪此问题不是 json 请求问题，而是我正在运行的查询的问题。我正在执行一个 INSERT ON DUPLICATE KEY UPDATE 查询，该查询会增加查询的文本大小。我可以从命令行运行此查询查找，但是从 PHP 中它失败了。目前正在调查这个问题。任何有兴趣的人都可以在此处查看查询..

** 这是用于 php 的 mysqli 插件的错误，出于某种原因，数据库处理程序不喜欢此代码。如果/当我有时间进行适当的测试时，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位。我注意到我的 firephp 输出中有一个错误，它无法从 POSTed 表单解析 XML。然后我让它输出 strlen() 和数据并注意到它正在将它从大约 7k 字节减少到 268(或 256 或我忘记确切数量的东西)。这使它成为不完整且无效的 XML 数据堆。我改用 $.post() 方法解决了这个问题。完美运行。
