sum.php

Return the sum of the values in an array.


    
                    sum(mixed $numArray) : string

This helper wraps the ArangoDB AQL function SUM(numArray) which calculates the sum of all numeric values in the given array.

Example AQL usage:

SUM([1, 2, 3, 4])             // returns 10
SUM(doc.scores)               // returns sum of all scores
SUM([5, 10, 15])              // returns 30

example

use function oihana\arango\db\functions\numerics\sum;

$expr = sum('[1, 2, 3, 4]');
// Produces: 'SUM([1, 2, 3, 4])'
