Question

嘿，我有一个数组，我希望在数组的不同级别对第一级子项的值求和。

<?php
$group = Array('Electronics' => Array(
                   '6 - Cameras & Supplies' => Array(
                'Cameras' => Array(

                }
            }
        }

?>

我想用下一级缩进值的总和替换输出中的“SUM”。

这不是最有效的方法，但您可以创建一个递归计算数组总和的函数：

function array_sum_recursive($array)
{
    $sum = 0;

    array_walk_recursive($array, function($item) use (&$sum) {
        $sum += $item;
    });

    return $sum;
}

PHP中的PHP Sum Children
