array_sum

(PHP 4 >= 4.0.4)

array_sum --  Calculate the sum of values in an array.

Description

mixed array_sum ( array array)

array_sum() returns the sum of values in an array as an integer or float.

Note: PHP versions prior to 4.0.6 modified the passed array itself and converted strings to numbers (which most of the time converted them to zero, depending on their value).
