Do zsumowania elementów zawartych w dowolnej tablicy wystarczy zastosowanie bardzo prostego rozwiązania.

Przykład:

Kod: php

<?php
$liczba[]=3;
$liczba[]=2;
$liczba[]=7;
$liczba[]=1;

echo array_sum($liczba);
//Wynik: 13
?>

W powyższym przykładzie używając funkcji array_sum() spowodowaliśmy zsumowanie wszystkich elementów tablicy $liczba, co dało nam wynik 13.
