我有一个应用程序，可以将一组 GPS 字符串写入文本文件，如下所示：
[{“日期”：“2017年2月13日19:26:00”，“时间”：1486974360428，“经度”：151.209900，“纬度”：-33.865143}{“日期”：“02/13/2017 19:26:13","时间":1486974373496,"经度":151.209900,"纬度":-33.865143}{"日期":"02/13/2017 19:26:23","时间":1486974383539, “经度”：151.209900，“纬度”：-33.865143}{“日期”：“02/13/2017 19:26:33”，“时间”：1486974393449，“经度”：151.209900，“纬度”：-33.865143} {“日期”：“2017年2月13日19:26:43”，“时间”：1486974403423，“经度”：151.209900，“纬度”：-33.865143}{“日期”：“02/13/2017 19： 26:53","时间":1486974413483,"经度":151.209900,"纬度":-33.865143}]
文件始终以
[]此文件被上传到 Ubuntu 服务器：
'filepath'/uploads/gps/'device ID'/'year-month-day'/'UTC download time'.txt
例如
/uploads/gps/12/2017-02-12/1486940878.txt
文本文件是在文件上传到服务器时创建的，因此每天会写入多个文件。
我想要一种方法将值写入 MySQL 数据库，标题为设备（从文件路径获取）、日期、时间、经度、纬度。
最初，最好只使用一个可以在服务器上运行的命令，最终我可以从管理面板上的 PHP 命令运行该命令。
我从哪里开始？
您可以轻松地将文本提交到服务器上的 PHP 程序，而不是上传。它将使用 JSON 解码将其转换为数组，然后将每条记录保存到表中。设备 ID 将是脚本的参数之一。
使用这种方法可以消除很多问题，例如不导入文件两次、导入后重命名/移动文件、查找文件等。
这也意味着每次发送数据时您的数据都是最新的。
这样的脚本编写起来非常简单，但它应该内置某种类型的安全性，以防止未经授权的实体发送数据。
这里有一些示例代码，用于处理文件并将它们存储到数据库中。我删除了您需要编辑的某些信息（用户 ID/密码数据库名称）。比我想象的要长一点，但仍然很短。如果您需要更多信息，请PM我。
