Question

I have a question involving PHP arrays and adding up the values.

I have an access database with information in this scheme

----------------------
| time | code        |
|------|-------------|
| 600  | broke down  |
| 500  | broke down  |
| 300  | waiting     |
| 200  | waiting     |
| 400  | remove coil |

Anyways, you get the idea. I have multiple code values, but can have multiple time values for one code. What I am trying to accomplish with PHP is to add up all time values and only display one code value.

The result I want would be:

1100 | Brokedown (600 & 500 added together)
500  | Waiting (300 & 200 added together)
400  | Remove Coil

Just for example. I think I should be using a multidimensional array, but I just cannot seem to wrap my head around what to do exactly with it. A point in the right direction would be greatly appreciated.

Answer 1

Why not SQL?

SELECT Code, Sum([Time]) 
FROM Table
GROUP BY Code

Time is a reserved word, so I guess it is an imaginary name. If it is real, you must enclose it in square brackets, or better, change it.
