I would like to do add some if else statement on my for each.

I just want to set no value data to display as None.

and if it has value then it will return the data.

TABLE : wp_events_answer

╔════╦══════════════╦════════════╗
║ id ║  answer      ║question_id ║
╠════╬══════════════╬════════════╣
║  1 ║ Maybank      ║   12       ║
║  2 ║ no value     ║   12       ║
║  3 ║ no value     ║   12       ║
║  4 ║ CIMB         ║   12       ║
╚════╩══════════════╩════════════╝

$number = 1;
foreach ($datas as $data) { 

    $result .= '<tbody>';                  
    $result .= '<tr>';
    $result .= '<td>';
    $result .= $number++;
    $result .= '</td>';

    $result .= '<td>';        
    $result .= $data->fname;
    $result .= '&nbsp;'; 
    $result .= $data->lname; 
    $result .= '</td>';

    $result .= '<td>';


    //#### PLEASE TAKE A LOOK HERE #####     
    if($result .= '')
    {
        $result .= 'None';
    }
    else
    {
        $result .= $data->answer;
    }

    //  #### END ####

    $result .= '</td>';
}
$result .= '</tr>';
$result .= '</table>';

return $result;

Use this

    if(empty($data->answer))
    {
        $result .= 'None';
    }
    else
    {
        $result .= $data->answer;
    }
