Question

我正在开发一个扫描仪项目，其中一个类读取由扫描仪创建的txt文件，并查询数据库以通过每个房间的扫描仪显示“捆绑”扫描仪。但是现在我有一些房间会复制结果。查询的结果是每天在数组中停止并进行操作。我想要做的是显示唯一的捆绑并删除重复项，留下最早的条目。下面是我的索引页面。任何提示建议将不胜感激。

Answer 1

在追加之前进行in_array()测试。

Answer 2

在查询中实现约束可能比在PHP中实现约束更好。尝试使用group by并在你的约会时使用min来获得最早入场的房间。 Here is a relevant example on this site.

如果您希望在PHP中执行此操作，则必须使用某些过滤器。设置临时数组以存储最终结果，并循环显示所有结果。如果房间不在结果数组中，请添加它。如果是，请比较日期并使用最早的日期。
