我在表中显示带有分页的文本文件记录以及他们想要查看功能的记录数。 不，我正在尝试添加新功能，用户可以根据表列对表数据进行排序。所以我在表格标题的右侧添加了排序选项。
现在我的问题是，Sorting工作正常但它不是基于列。 请告诉我，我做错了什么？
这是我的PHP脚本

这是我正在阅读的文本文件数据
注意：代码更新
更新1：
我创建了基于列进行排序的函数，但它无法正常工作。
我正在接受这个问题的帮助
Sort PHP multi-dimensional array based on key?
它适用于地址，但不适用于浮点数。

答案 0 :(得分：0)
我修改了我的脚本并尽可能地优化它。 现在它按照我的要求正常工作。每个列都有排序选项，当我们进行排序时，则使用分页和每页记录选项对列进行排序。
如果有人在寻找类似的脚本，那么这可能会有所帮助
