如何在php中的多个下拉框中设置搜索过滤器选项？

Question

我的结果来自特定的api。我没有数据库。我正在使用bootstrap表进行分页和列，行对齐。如何在客户端本身或使用php，ajax？

进行搜索过滤器下拉列表

例如

          <table id="example" class="table table-striped table-bordered"        cellspacing="0" width="100%">
           <thead>
             <tr>
                <th>Date</th>
             <th>Caller</th>
              </tr>
            </thead>
       [objects] => Array
    (
        [0] => Array
            (
                [customer_name] => dominic

                [start_time] => 2017-06-23 08:40:32+05:30

            )

    [19] => Array
            (
         [customer_name] => celestine

                [start_time] => 2017-06-23 08:40:32+05:30
    )


)
       <?php foreach($json['objects'] as $res){ ?>
             echo '<tr>';
             echo '<td>'.$res['customer_name'].'</td>';
                echo '<td>'.$res['start_time'].'</td>';
             echo '</tr>'   
       <?php } ?>
            </tbody>
       </table>
      <select onchange="functioname()">
       <option>Dominic</option>
      </select>
          <select id="date">
       <option>date</option>
      </select>
