Codeigniter上传excel并保存到数据库（网络错误（tcp_error））
真的需要你的支持。 在我们决定将其上传到公开之前，这在Intranet上有效。
我正在使用Codeigniter + SQL Server + Apache
这应该如何运作： 上传excel文件，阅读内容，保存到数据库并发送电子邮件＆amp;短信。
但：
每次我在3分钟后上传excel文件时它会停止并在Developer Opt-＆gt; Network Tab上写下这个错误：
“网络错误（tcp_error）
发生通信错误：“”
Web服务器可能已关闭，太忙或遇到阻止其响应请求的其他问题。您可能希望稍后再试。“
这是我的代码：

我通过CRON作业或在我的PHP脚本上调用cmd命令解决了这个问题，这样它就可以非常快速地在服务器上执行查询。 ：）
