Question

我正在尝试将这两个数组中的gq_numplay添加到一起并回显总数。任何人都可以阐明我如何做到这一点吗？

感谢。

Array
(
    [1] => Array
    (
            [dedicated] => d

        )

    [2] => Array
        (

            [coop] => 0

        )
)

我已经能够从每个数组中提取单个值，但我不能将它们加在一起：（

Answer 1

你错过了那里被转储的变量的名称，但是假设它是$ foo，试试

echo $foo[1]['gq_numplayers'] + $foo[2]['gq_numplayers'];

Answer 2

使用foreach循环遍历每个元素：

$total = 0;
foreach($arr as $x) {
  $total += $x['gq_numplayers'];
}

echo $total;

在数组中添加数组中的结果
