Summing values from a flat array

Question

I'm trying to sum all the values inside an array, I've tried using count() but to no avail, the array values may also have negatives in them, example:

Array
(
    [name] => 1
    [phone] => 1
    [emailX] => 1
    [car] => 0
    [finance] => 2
    [employed] => 1
    [credit] => -5
)

If you sum all of them together, the result should be 1, I'm just not sure how to go about it.

You can use array_sum():

$sum = array_sum($myArray);

The count() function gives you the number of items in the array.

count will return the number of elements, you will want to use array_sum

$sum = array_sum($arr);
