因为您的 json 有多个嵌套数组，您也需要迭代这些数组。所以我们检查我们的值是否是一个数组，如果是的话我们使用另一个 foreach 循环。

<?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>

                  <?php       }
                        } else { ?>

                  <tr>
                        <td><?php echo $key; ?></td>
                        <td><?php echo $element; ?></td>
                        <td></td>
                  </tr>

                  <?php }
                  }

            } else {   ?>

            <tr>
                  <td><?php echo $key; ?></td>
                  <td><?php echo $value; ?></td>
                  <td></td>
            </tr>

      <?php }
      } ?>
</table>
