如何在 html table（日历）中将行值加在一起？
How to add row values together in a html table (calendar)?
我有一个使用 html table 用 php 制作的日历。
每个日期都有一个从数据库中插入到天数下方的整数值。
我想要做的是获取 table 的每一行（周）的总和并将其放入第 8 列。我怎样才能做到这一点？
有什么帮助吗？

以上代码输出如下：
I just went through your script, put all total miles into an array
and calculate sum with
array_sum
