Re: how to sum array items, vertically?

Yeah, sorry, was posting late at night :P I am getting time-durations from a database, aggregating them per week (with a few conditions), so that I go from data like this: 2001-10-01, 4:30, 2 (ie, "person 2" did a "4 hour, 30 min" peice of work on a certain date). to this: date = hours work by person1, person2, person3, person4 .... 2001-01-01 = 23, 45, 12, 45, 02, as in: The reason i'm doing it in this way, is because I need to do a bit of shifting around of hours when people worked over midnight etc. Anyway, when I get to the end; 2001-01-01 = 23, 45, 12, 45, 02 2001-01-08 = 3, 15, 2, 35, 8 etc etc ... I want to see the total (and the average, but thats easy) hours worked by each person.
