php 根据时间排序,接近的时间排在前面,过去的时间排在后面

产品需求,有一个开放日的活动,时间是多选,且一个时间不能超过24小时,不能跨天,不能相等,后台没问题了,接口调取数据的时候麻烦点,因为刚开始时间存的json字段,后面改为添加一个时间表
时间字段有:stime:开始时间,etime:结束时间

// 接收的时间因为前台可以切换月份查看数据
$deta = $this->request->post('deta'); // 2023-12-10
// 转为年月
$dateParam = date('Y-m',strtotime($deta));
$currentMonthStart = $dateParam;
$currentMonthStart = date('Y-m-d 00:00:00', strtotime($currentMonthStart));
$currentMonthEnd = date('Y-m-t 23:59:59', strtotime($currentMonthStart));
// 注释的内容是上一测试的方法
$result = opmodel::alias('a')->join('opendaytime op', 'op.openday_id = a.id', 'left')
    ->where([
        'a.switch'=>1,
        'op.stime'=>['>',$currentMonthStart],
        'op.etime'=>['<',$currentMonthEnd]
    ])
    // 将 GROUP_CONCAT(DATE_FORMAT(op.stime, "%Y-%m-%d"))转换为年月日
//            ->field('a.*,GROUP_CONCAT(op.id) as opid,CONCAT("[", GROUP_CONCAT(JSON_OBJECT( "etime", DATE_FORMAT(op.etime, "%Y-%m-%d %H:%i:%s"),"stime", DATE_FORMAT(op.stime, "%Y-%m-%d %H:%i:%s"))), "]") as optime')
    ->field('a.*,op.id as opid,op.stime,op.etime,op.openday_id')
//            ->group('a.id')
    ->order('stime')
//            ->fetchSql()
    ->paginate($limit,$pages)->toArray();
// 根据openday_id将相同的数据归为一个数组
 $newData = [];
