Laravel: How to remove item from multidimensional collection by value

So my output is something like this, but can vary:

{
    "4": {
        "position": "0",
        "type_id": "1",
        "miles": "0",
        "drop_hooks": "0",
        "different": "off"
    },
    "8": {
        "position": "1",
        "type_id": "3",
        "miles": "0",
        "drop_hooks": "0",
        "tray_count": "0",
        "roll_offs": "0",
        "pack_outs": "0",
        "different": "off"
    }
}

How can I remove (unset) any item (miles, drop_hooks, tray_count, etc) that is equal to zero?

Note: Sometimes position can be zero. I do not want to remove/unset position from the collection.

Edit: Desired Result:

{
    "4": {
        "position": "0",
        "type_id": "1",
        "different": "off"
    },
    "8": {
        "position": "1",
        "type_id": "3",
        "different": "off"
    }
}

Here is a double loop solution starting from collection

$groups = $collection->toArray();
foreach($groups as $groupIndex => $group) {
    foreach($group as $attName => $attValue) {
        if ($attValue === "0" && $attName != "position") {
            unset($groups[$groupIndex][$attName]);
        }
    }
}
return json_encode($groups);

Simply apply array_filter to filter out unwanted content:


function filterEmpty(&$array) {
    $array = array_filter(
        $array,
        function ($key, $value) {
             return $key == 'position' || !is_numeric($value) || (int) $value > 0
        },
        ARRAY_FILTER_USE_BOTH
    );
}


array_walk($fooArray, 'filterEmpty');
