Description

mixed array_sum ( array array)

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

Пример 1. array_sum() examples
<?php $a = array(2, 4, 6, 8); echo "sum(a) = " . array_sum($a) . "\n"; $b = array("a" => 1.2, "b" => 2.3, "c" => 3.4); echo "sum(b) = " . array_sum($b) . "\n"; ?>
The printout of the program above will be:
sum(a) = 20 sum(b) = 6.9

Замечание: PHP versions prior to 4.2.1 modified the passed array itself and converted strings to numbers (which most of the time converted them to zero, depending on their value).
