array_sum() definition and usage
array_sum() function returns the sum of all values in the array.
If all values are integers, return an integer value. If one or more of the values is a floating point number, a floating point number is returned.
Pre-PHP 4.2.1 versions modified the passed array itself, converting the string values in it to numeric values (or zeros in most cases, depending on the system).
