我在php脚本中运行了一个相当密集的SQL查询，它基本上汇总了我们每个员工在电话上的号码，创建了一个CSV，然后通过PHP邮件程序将其附加到电子邮件中。
这种方法很好，但我的任务是把它变成一份完整的报告（即excel报告，格式化等），并为每位员工提供总计。现在它基本上只有每个员工的行项目，因此员工A可能有32个记录，然后它直接进入员工B.我需要更改它，以便在员工A的记录结束时，它插入一行总计每列的值。
我想我只能使用PHP来做这件事，因为这是一个PHP脚本，但我不知道这里最好的方法，我希望得到一些指导，我可以适用于查询的其余部分。
我认为为字段/列创建一个变量可能会很好，这样我就可以用这种方式创建一个SUM，但我对此表示满意。
这是脚本的SQL部分：
$result = mysqli_query($conn2,
"SELECT

正如您所看到的，它从代理7200发送到代理7206.但我需要在每列中插入一行总计那些x。
