Let just say i have this [{"id":21},{"id":22}] array coming up from this :

$schedules = [];
    foreach ($routes as $route) {
        $schedules[] =Schedule::select('id')
                        ->whereIn('route_id', $route)

So, i want to extract the value from it like this [21,22], so i did it like this:

$values = $schedules->pluck('id')->toArray();

this showing this error

Call to a member function pluck() on array

    To achieve what you're after with the code you have you can use array_map:

    $values = array_map(function ($item) {
        return $item->id;
    }, $schedules);

    Alternatively, you could simply get the id initially by either using ->first()->id or value('id'):

    foreach ($routes as $route) {
        $schedules[] =Schedule::select('id')
                        ->whereIn('route_id', $route)

    Use array_column to get just the values.

    $values = array_column($schedules->pluck('id')->toArray(),'id');

    You can first make a collection of it first and then use pluck.

    I assume you have the following data

    $schedules = [
        ["id" => 21],
        ["id" => 22]
    return collect($schedules)->pluck('id')->toArray();

    Demo here
