I'm having a hard time learning how to get an average. I have a database
that gets a number and inserts in into a MySQL database every 1/2 hour
during the day. For the current half hour, I want to get the last 15 days
numbers for the same time as the time it is now. I can retrieve and display
the numbers fine, I just don't know how to go about putting these all into
variables or an array or if I can do this within a query and then take an
average for them. Hope that made sense. Thanks.
