Question

How can I add all of my array values together in PHP? Is there a function for this?

Answer 1

If your array consists of numbers, you can use array_sum to calculate a total. Example from the manual:

$a = array(2, 4, 6, 8);
echo "sum(a) = " . array_sum($a) . "\n";

If your array consists of strings, you can use implode:

implode(",", $array);

it would turn an array like this:

strawberries
peaches
pears
apples

into a string like this:

strawberries,peaches,pears,apples
