[RESOLVED] Adding values in an array

revez2002

I recently began using an array to hold a couple of values from a database search result. The key for the array holds a percentage, and the value for the array holds a username.

I want to be able to sum all the values held in the array based on matching username. There is plenty of information about combining and sorting the array, and even summing all of the numeric values. However, I have been so far unable to find anything in the manual that describes how to do this.

Any quick tips?

I think the easiest way would be to sort the array and then loop through the elements one by one... adding them as you go until the username changes and then just echo the total out.

To get at the key and value as seperate variables you could use the following;

foreach ( $ArrayName as $Percentage => $Username )
{

// Now in here you can directly access the Percentage as $Percentage and Username as  $Username

}

Hope this helps...?

Yes, I was thinking that looping through with foreach might be the way to go, but I also thought that there might be a simpler method using one of the native array functions. I think I will give the foreach loop a try and see how it goes...

Thanks for the suggestion.
