Array_sum () Definition and usage
The Array_sum () function returns the sum of all the values in the array.
If all values are integers, an integer value is returned. Returns a floating-point number if one or more of the values are floating-point numbers.
The previous version of PHP 4.2.1 modifies the passed-in array itself, converting the string value into a numeric value (which in most cases is converted to 0, depending on the specific system).
