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
$newData = [];
foreach ($result['data'] as $item) {
$opendayId = $item['openday_id'];
