I create a telegram bot keaboard with laravel. There is a part of code.

```
$available_buttons =ReportToAbonent::select("report_id")
    ->join("telegram.reports", "report_to_abonent.report_id", "=", "reports.id")
    ->where("abonent_id", "=", $abonent[0]->id)
    ->where("active","=","1")
    ->get();

$keyboard = array();
foreach ($available_buttons as $value)
{
    $keyboard[] = array($value->report_id);
}

$reply_markup = \Telegram::replyKeyboardMarkup([
    'keyboard' => $keyboard,
    'resize_keyboard' => true,
    'one_time_keyboard' => false
]);

```

If I print 

```
$keyboard`, its structure looks like if `$keyboard = [
            ['7', '8', '9'],
            ['4', '5', '6'],
            ['1', '2', '3'],
            ['0']
        ];

```

But in first case no keyboard in telegram client. In the second case it is present. What can I do wrong.
