如何在引导日历php代码

我使用的是Bootstrap完整日历。它工作得很好，但当我添加PHP代码时，它就不能正常工作了。

这是我为task表获取所有数据的代码。当在日历内显示时，只显示最后一行，其余行不显示：

<script>
     
      $(function () {
        /* initialize the external events
         -----------------------------------------------------------------*/
        function ini_events(ele) {
          ele.each(function () {
            // create an Event Object (http://arshaw.com/fullcalendar/docs/event_data/Event_Object/)
            // it doesn't need to have a start or end
            var eventObject = {
              title: $.trim($(this).text()) // use the element's text as the event title
            };
            // store the Event Object in the DOM element so we can get to it later
            $(this).data('eventObject', eventObject);
            // make the event draggable using jQuery UI
            $(this).draggable({
              zIndex: 1070,
              revert: true, // will cause the event to go back to its
              revertDuration: 0  //  original position after the drag
            });
          });
        }
        ini_events($('#external-events div.external-event'));
