title: Telegram bot keyboard
body: <p>I create a telegram bot keaboard with laravel. There is a part of code.</p>
  
  <pre><code>$available_buttons =ReportToAbonent::select("report_id")
      -&gt;join("telegram.reports", "report_to_abonent.report_id", "=", "reports.id")
      -&gt;where("abonent_id", "=", $abonent[0]-&gt;id)
      -&gt;where("active","=","1")
      -&gt;get();
  
  $keyboard = array();
  foreach ($available_buttons as $value)
  {
      $keyboard[] = array($value-&gt;report_id);
  }
  
  $reply_markup = \Telegram::replyKeyboardMarkup([
      'keyboard' =&gt; $keyboard,
      'resize_keyboard' =&gt; true,
      'one_time_keyboard' =&gt; false
  ]);
  </code></pre>
  
  <p>If I print </p>
  
  <pre><code>$keyboard`, its structure looks like if `$keyboard = [
              ['7', '8', '9'],
              ['4', '5', '6'],
              ['1', '2', '3'],
              ['0']
          ];
  </code></pre>
  
  <p>But in first case no keyboard in telegram client. In the second case it is present. What can I do wrong.</p>
