PHP | Compare two arrays

Question

I have two arrays:

$arr_order:

   Array
    (
        [0] => Array
            (
                [qty] => 5
                [id] => 2
                [sku] => Model 2
            )

        [1] => Array
            (
                [qty] => 2
                [id] => 3
                [sku] => Model 1
            )
    )

$arr_stock:

Array
(
    [0] => Array
        (
            [id] => 2
            [qty] => 2
        )

    [1] => Array
        (
            [id] => 3
            [qty] => 2
        )

)

How can I compare these two arrays using a foreach loop?

Example: If $arr_order[0][qty] =5 > $arr_stock[0][qty] = 2 ...

returns third array:

$arr_stock_available:

Array
    (
        [0] => Array
            (
                [id] => 2
                [qty] => 2
            )
    )

Hint: foreach ($arr_order as $i => $val) $arr_stock[$i]['qty'] ... — deceze

Use array_diff to get the diferences: php.net/manual/en/function.array-diff.php — Gimmy

$i = 0;
$arr_stock_available = array();
foreach($arr_order as $data){
   if($data['qty'] > $arr_stock[$i]['qty']){
       $arr_stock_available[] = $arr_stock[$i];
    } else {
       $arr_stock_available[] = $data;
    }
    $i++;
}

Use the above code.

For one, you're never incrementing $i, secondly the OP wanted the difference between the stock values.

@deceze I have modified the code. But not found anywhere that OP want the difference of stock values.

@user889349 if you want only the result as you show the above then remove the else part from my answer.

Thanks! Else condition can be removed.
