Hi Everyone,

I have this array:

Array
(
    [0] => Array
        (
            [productid] => 16141
            [amount] => 1
        )

    [1] => Array
        (
            [productid] => 129
            [amount] => 1
        )

    [2] => Array
        (
            [productid] => 16141
            [amount] => 1
        )

)

I was wondering if there was a function that would take the values of the array and add up the amounts or identical productids so that the result would look something like this:

Array
(
    [0] => Array
        (
            [productid] => 16141
            [amount] => 2
        )

    [1] => Array
        (
            [productid] => 129
            [amount] => 1
        )


)

I looked on php.net, but either I am missing it or it doesn't exist. Hopefully someone knows how to do this.

Thanks
