如何在php中计算多维数组中的值

我有一个多维数组，我想用total这个名字对所有的值求和，这里是一个例子

[1] => Array
    (
        [id] => 829
        [tok] => f3404ba92a40f7
        [user_id] => 1
        [total] => 10000
        [created_at] => 2020-12-03 00:18:09
    )

[2] => Array
    (
        [id] => 830
        [tok] => 2669483afacc47
        [user_id] => 1
        [total] => 2000
        [created_at] => 2020-12-03 00:18:12
    )

[3] => Array
    (
        [id] => 831
        [tok] => 9b72ba6ab4d8d0
        [user_id] => 1
        [total] => 5000
        [created_at] => 2020-12-03 00:18:14
    )

我想对数组中的所有总数求和

类似这样的？只需更改变量名的

$data

$sum = 0;

foreach ($data as $row) {
    $sum += $row['total'];
}

echo $sum; // 17000
