Php 可执行文件有更多数据要发送，但don'；I don’我不知道如何向可执行文件发出信号，表示已经发送的数据已被处理并准备好下一个块

全部

这是我在这里的第一个问题，如果我犯了错误，请告诉我。我想尽我所能去学习

话虽如此，我的困境就在这里

我正在尝试修改一些php，以便Microsoft Flight Simulator用作ACARS的程序可以向我的代码发送日志文件，并将数据写入MySQL数据库。我提到的程序将数据分解成1Kb的块，发送第一位，等待代码响应OK beofre再发送下一位，依此类推，直到所有数据都被检索并写入文件（txt）和数据库。这一切都可以很好地进行修改。这是未修改的代码

我知道这是很多代码，我很抱歉，如果有更好的地方让像我这样的初学者获得帮助，我渴望去那里尝试。我已经仔细研究了一个月，似乎有些事情很简单，但我就是没看到。任何帮助都将不胜感激

我找到了解决办法。事实证明，每次接收到数据包时，整个脚本都会循环执行，第一个函数实际检查是否存在任何内容。否则，脚本将停止。我可以使用

if(strpos($pirep[$i],"TOD Land)!==FALSE) {
include("processdcapirep.php; }

---

检查日志文件的最后一行。这样，它就不会调用我的查询，直到整个文件都被写入。我很感激收到的每一个回复。这里好像有很多人

我看不出有什么问题？你有错误吗？它不停吗？或者寻求帮助的人应该搜索什么？对不起，我没有提到实际问题！正在讨论的程序是FSAcars，可在以下网址找到。未修改的php代码将接收到的数据分解为1KB的数据块，并将其写入文本文件和数据库。如果我修改代码以包含注释并添加到另一个表中，php会在第一个块后停止，并留下大量字符串为空，从而导致MySQL错误。“在主函数下”？不是“在主功能内部”？提示：尝试手动访问脚本，例如通过web浏览器或通过命令行传递必要的参数。查看是否报告了任何错误。检查PHP错误日志（如果有）。同样在你的代码中，“打开并将数据附加到数据库”部分应该使用mysql\u查询而不是mysql\u结果。不确定我怎么会错过这个，lmz。明天我会试试看，因为今晚很晚，明天是工作日。我会发布结果……有没有办法截取FSAcars创建的URL中发送的数据，以便我可以通过浏览器进行检查？否则的话，我得花相当长的时间来检查变化。
