How to access object inside Foreach?

My array looks like this:

Array

(

[id] => 196011470503479_873596956078257

[message] => #Dabur India Ltd has been ranked amongst India's Super 50 Companies by Forbes India. The annual list ranks companies that generate high returns for investors, grow their Revenues strongly and deploy funds efficiently.

[created_time] => DateTime Object

    (

        [date] => 2016-07-29 04:00:01.000000

        [timezone_type] => 1

        [timezone] => +00:00

    )



[shares] => Array

    (

        [count] => 26

    )

PHP Code

</tbody>

    <?php

        $i = 1;

        foreach($arr['posts'] as $poInd=>$poVal){

            echo "

                <tr>

                    <td>".$i."</td>

                    <td>".$poVal['id']."</td>

                    <td>".$poVal['name']."</td>

                    <td>".$poVal['message']."</td>

                    <td>".($poVal['created_time']->date)."</td>

                    <td>".$poVal['shares']['count']."</td>

                    <td>".count($poVal['likes'])."</td>

                    <td>".count($poVal['comments'])."</td>

                </tr>

            ";

            $i++;

        }

    ?>

</tbody>
