Print JSON output to table - PHP

Since your json has multiple nested arrays, you need to iterate over them as well. Therefore, we check if our value is an array if we use another foreach loop.

<?php
$json = '{"response_code":200,"pnr":"6642876935","train_num":"12792","train_name":"PNBE SC EXP    ","doj":" 6- 7-2015","from_station":{"code":"PNBE"},"to_station":{"code":"SC"},"reservation_upto":{"code":"SC"},"boarding_point":{"code":"PNBE"},"class":"SL","no_of_passengers":"1","chart_prepared":"N","passengers":[{"sr":"1","booking_status":"W\/L   43,GNWL","current_status":"RAC   19"}],"noms":1,"error":null}';
$data = json_decode($json, true);
?>

<table> 
      <tr>
            <td>Key</td>
            <td>Value</td>
            <td>Value</td>
      </tr>
      <?php foreach($data as $key => $value){ 

            if(is_array($value)){
                  foreach($value as $element){  
                        if(is_array($element)){
                              foreach($element as $key2 => $child){?>

                                    <tr>
                                          <td><?php echo $key; ?></td>
                                          <td><?php echo $key2; ?></td>
                                          <td><?php echo $child; ?></td>
                                    </tr>
