About calculations in $row



Employee number, name, no, object name, travel distance, arrival time, departure time can be obtained directly from the database $row ["]
Drive time, travel speed, operating time need to be calculated to get
Job time I get it this way
Acquisition of travel speed

Question 1: This travel time is described in Excel, such as Zhangsan's no=2 behavior i3-j2 and so on I4-j3,i5-j4,. Can this be handled, is there any way to $row+1 the wrong line calculation?
Question 2: Requirements are grouped by name is it better to use GROUP by? Can I use ORDER by?
Question 3: After each person, there is also a total, such as the need to calculate travel distance and, travel time, and the time of the work, and how to deal with this part?
Question 4: Does the whole work content be easier to handle with Phpexcel?

Thank you
