FullCalendar - 如何为DB中的每个用户加载计划

Question

I am using FullCalendar. When I add a schedule, I store the phone numbers of users in the database. When fetching, I want to fetch the schedule separated by user phone number in PHP. What should I do?

test.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'],
                                           start: value['start'],                                                                
                                           title: value['title'],                                                                                                    
                                           end: value['end']
                                      });                                                                                       
                                });

                       callback(events);

            $.ajax({
