following is my array

Array(
[id] => 1
[user_id] => 30
[list] => Array
    (
        [0] => Array
            (
                [id] => 1
                [card_id] => 6
                [amount] => 400
            )

        [1] => Array
            (
                [id] => 2
                [card_id] => 3
                [amount] => 500
            )

    )
)

from above array i want to get values of amount key which is in list key. i want to store that values in one variable. P.S : In list array it will have multiple arrays

Edit: there should be sum of all amount in output. for example from above array sum woulld be 900 is $total_amount = 900

Reset to default

One liner with array_column and array_sum;

echo array_sum(array_column($array["list"], 'amount')); // 900

Here is what you want, simple foreach:

$array = [
"id" => 1,
"user_id" => 30,
"list" => [
            [
                "id" => 1,
                "card_id" => 6,
                "amount" => 400,
            ],

        [

                "id" => 2,
                "card_id" => 3,
                "amount" => 500,
        ]

    ]
];

$totalAmount = 0;

foreach ($array["list"] as $array){
  $totalAmount += $array["amount"];
}

var_dump($totalAmount);

Result: 900
