Question

i have this array:

[Jessica CS] => Array
    (
        [2011-04-20] => Array
            (
                [0] => 69.90
                [cancel] => 1311145200
                [1] => 29.95
                [2] => 69.90
            )
    )

[Rex CS] => Array
    (
        [2011-04-20] => Array
            (
                [0] => 119.94
                [cancel] => 
            )

        [2011-04-26] => Array
            (
                [0] => 199.50
                [cancel] => 
                [1] => 29.95
            )
....

and i am adding together these values by using a loop:

$i=0;
foreach($dates as $d){
$total[$i] += array_sum($value[$d]);
#i++;
}

this will add everything together and what i want is to exclude the [cancel] field from being added to the array_sum

edit: i could probably add the values that are int, but not sure how to sort them

any ideas?

thanks

Answer 1

Personally I would change the layout of the array so that it went more like:

[Jessica CS] => Array
    (
        [2011-04-20] => Array
            (
                [cancel] => 1311145200
                [costs] => Array
                    (
                        [0] => 69.90
                        [1] => 29.95
                        [2] => 69.90
                    )
                )
    )

Replacing [costs] with whatever name is most relevant.

Working with your existing array
Failing that

$i=0;
foreach($dates as $d){
    $total[$i] += array_sum(array_diff_key($value[$d], array('cancel'));
    #i++;
}
