我正在使用fullcalendar。当我添加时间表时，我将用户的电话号码存储在数据库中。在获取时，我想获取用php中的用户电话号码分隔的时间表。我该怎么办？
测试.js

var calendar = $('#calendar').fullCalendar({
    height:650,
    locale:'ko',
    editable: true,
    header:{
         left:'prev,next today',
         center:'title',
         right:'month,agendaWeek,agendaDay,listDay'
     },
   events: function(start,end,callback){
                var pno="2154421215";
                $.ajax({
                       url: 'fetch-event.php',
                       data: {pno:pno}, 
                       type: "POST",   
                       success: function (obj) {
                                var events = [];
                                $.each(obj, function(index, value) {
                                      events.push({
                                           id: value['id'],

fetch-event.php文件

<?php
