php 日历代码

日历的PHP接口代码：

$user_id = $_SESSION['user_id'];
    $year = isset($_REQUEST['tty']) ? intval($_REQUEST['tty']) : date('Y');
    $month = isset($_REQUEST['ttm']) ? intval($_REQUEST['ttm']) : date('m');
    //获取当前月有多少天
    $days = date('t', strtotime("{$year}-{$month}-1"));
    // 当前1号是星期几
    $week = date('w', strtotime("{$year}-{$month}-1"));
    // 实现上一月和上一年
    if ($month == 1) {
        $premonth = 12;
        $preyear = $year - 1;
    } else {
        $premonth = $month - 1;
        $preyear = $year;
    }
    // 实现下一月和下一年
    if ($month == 12) {
        $nextmonth = 1;
        $nextyear = $year + 1;
    } else {
        $nextmonth = $month + 1;
        $nextyear = $year;
    }
    $dayss = array();
    for ($i = 1; $i <= $week; $i++) {
        $dayss[] = '';
    }
    for ($i = 1; $i <= $days; $i++) {
        $dayss[] = $i;
    }
    // 获取签到所有数据（本月中）
    $start = strtotime("{$year}-{$month}-1");
    $end = strtotime("{$nextyear}-{$nextmonth}-1") - 1;
    $logsql = 'SELECT * FROM ' . $ecs->table('hpyer_sign_log') . " where uid={$user_id} AND add_time between {$start} AND {$end}";
    $loglist = $db->getAll($logsql);
    $loginfo = array();
    foreach ($loglist as $v) {
        $loginfo[] = intval(date('d', $v['add_time']));
    }


    $result = array(
        'code' => 1,
        'data' => array(
            'year' => $year,
            'month' => $month,
            'preyear' => $preyear,
            'premonth' => $premonth,
            'nextyear' => $nextyear,
            'nextmonth' => $nextmonth,
            'days' => $dayss,
            'loginfo' => $loginfo
        )
    );
    die($jsonr->encode($result));

HTML接口说明：

$('.riQh').on('click', function() {
    var tty = $(this).attr('tty'),
        ttm = $(this).attr('ttm');
    $.ajax({
        url: '/mobile/ajaxnew.php',
        data: {
            act: 'rili',
            tty: tty,
            ttm: ttm
        },
        type: 'post',
        dataType: 'json',
        success: function(res) {
            console.log(res);
            if (res.code == 1) {
                $('.riz').attr('tty', res.data.preyear);
                $('.riz').attr('ttm', res.data.premonth);
                $('.riy').attr('tty', res.data.nextyear);
                $('.riy').attr('ttm', res.data.nextmonth);
                $('#nowdate').text(res.data.year + '年' + res.data.month + '月');
                var zoninfo = '';
                for (var i = 0; i < res.data.days.length; i++) {
                    if(res.data.loginfo.indexOf(res.data.days[i]) >-1){
                        zoninfo += '<li class="active">'+res.data.days[i]+'</li>';
                    }else{
                        zoninfo += '<li>'+res.data.days[i]+'</li>';
                    }
                }
                $('#rilihtml').html(zoninfo);
