我正在通过 JSON 编码的 ajax 请求（表单流程）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，并正确接收了结果。在请求中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 段错误。只有 2 个字段，一个用于 3 位 id，其余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

有人有想法么...

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 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这个查询 find ，但是从 PHP 中它失败了。目前正在调查该问题。任何有兴趣的人都可以在这里查看查询..

** 这是 php 的 mysqli 插件的一个错误，由于某种原因，db 处理程序不喜欢此代码。如果/当我有时间正确测试时，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位。我注意到我的 firephp 输出中有一个错误，它无法解析 POSTed 表单中的 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）。这使其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。工作完美。

您可以简单地检查字符串的长度，如果超过限制，请将其拆分。在插入中运行第一部分，然后+=使用第二部分对字段进行更新。这有点粗糙，但它绕过了这个错误。
