Simple question: How do I add the contents of an array?

[Michdd]

I know it's using a foreach() statement, but how would I go about adding the contents of an array to get a total.

 

Example:

 

$number[0] = "1";
$number[3] = "5";

 

I want it to add all the numbers within a certain array to get total.

Actually, there is a php function for summing values in an array, coincidentally named "array_sum"

 

<?php
$a = array(2, 4, 6, ;
echo "sum(a) = " . array_sum($a);
?>

(from http://us2.php.net/array_sum)
