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
2023-12-14 18:26:07
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 = $item['openday_id'];
if (!isset($newData[$opendayId])) {
$newData[$opendayId] = [
'id'=> $item['id'],

$newData[$opendayId]['optime'][] = [
'stime' => $item['stime'],
'etime' => $item['etime'],

}
// 当前时间
$currentTimestamp = strtotime(date('Y-m-d 00:00:00'));
// 循环处理时间，添加未来时间futuretime和过去时间pasttime
foreach ($newData as &$activity) {
$activity['futuretime'] = ''; // 未来时间
$activity['pasttime'] = []; // 过去时间
foreach ($activity['optime'] as &$optime) {
$startTime = strtotime($optime['stime']);

$activity['futuretime'] = $startTime;
}
}else{
$activity['pasttime'][] = $startTime;
}
// $ymd 暂未使用
$ymd = date('Y-m-d', strtotime($optime['stime']));
$_ymd = date('Y-m', strtotime($optime['stime']));
$hm = date('H:i', strtotime($optime['stime'])) .'-'.date('H:i', strtotime($optime['etime']));
if (!$activity['currentmonth']) {
$activity['currentmonth'] = explode('-', $_ymd);
}
// 特殊需求 展示时间
$activity['ymdhm'][] = [
'ymd' => $_ymd,
'hm' => $hm,
];
}
// 前台点击查看的月份
$activity['cktime'] = date('Y-m',strtotime($activity['optime'][0]['stime']));
// 统计当前月份的场次
$activity['counttime'] = count($activity['ymdhm']);
$activity['school_name'] = $activity['school_id'];
// 可去可不去
unset($activity['openjson']);
// 如果futuretime没有数据，就将最后一个日期放入
if (empty($activity['futuretime'])) {
$lastOptime = end($activity['optime']);
$lastStartTime = strtotime($lastOptime['stime']);
$activity['futuretime'] = $lastStartTime;
}
}
// 根据字段排序
usort($newData, function($a, $b) use ($currentTimestamp) {
if ($a['futuretime'] < $currentTimestamp) {
return 1;
} elseif ($b['futuretime'] < $currentTimestamp) {
return -1;
} else {
