一、获取时间 1、获取本周一 date('Y-m-d', (time() - ((date('w') == 0 ? 7 : date('w')) - 1) * 24 * 3600)); //w为星期几的数字形式,这里0为周日 2、获取本周日 date('Y-m-d', (time() + (7 - (date('w') == 0 ? 7 : date('w'))) * 24 * 3600)); //同样使用w,以现在与周日相关天数算 3、获取上周一 date('Y-m-d', strtotime('-1 monday', time())); //无论今天几号,-1 monday为上一个有效周未 4、获取上周日 date('Y-m-d', strtotime('-1 sunday', time())); //上一个有效周日,同样适用于其它星期 5、获取本月一日 date('Y-m-d', strtotime(date('Y-m', time()) . '-01 00:00:00')); //直接以strtotime生成 6、获取本月最后一日 date('Y-m-d', strtotime(date('Y-m', time()) . '-' . date('t', time()) . ' 00:00:00')); //t为当月天数,28至31天 7、获取上月一日 date('Y-m-d', strtotime('-1 month', strtotime(date('Y-m', time()) . '-01 00:00:00'))); //本月一日直接strtotime上减一个月 8、获取上月最后一日 date('Y-m-d', strtotime(date('Y-m', time()) . '-01 00:00:00') - 86400); //本月一日减一天即是上月最后一日 9、获取当前时间前6天 date('Y-m-d', strtotime('-6 days')); 10、指定时间加一个月 date("Y-m-d",strtotime("+1 month",strtotime("2012-02-04"))); 11、指定时间加一周 date("Y-m-d",strtotime("+1 week",strtotime("2011-02-04"))); 12、指定时间加一天 date("Y-m-d",strtotime("+1 day",strtotime("2011-02-04"))); 13、当前时间加一天 date('Y-m-d H:i:s',strtotime('+1 day')); 14、当前时间加一小时 date('Y-m-d H:i:s',strtotime('+1 hour')); 15、当前时间加一分钟 date('Y-m-d H:i:s',strtotime('+1 minute')); 16、当前时间加一月 date('Y-m-d H:i:s',strtotime('+1 mouth')); 17、获取当前月的第一天和最后一天 $date = date('Y-m-d'); function getMonth($date){ $firstday = date("Y-m-01",strtotime($date)); $lastday = date("Y-m-d",strtotime("$firstday +1 month -1 day")); return array($firstday,$lastday); } 18、获取上月的第一天和最后一天 $date = date('Y-m-d'); function getlastMonthDays($date){ $timestamp=strtotime($date); $firstday=date('Y-m-01',strtotime(date('Y',$timestamp).'-'.(date('m',$timestamp)-1).'-01')); $lastday=date('Y-m-d',strtotime("$firstday +1 month -1 day")); return array($firstday,$lastday); } 19、获取下月的第一天和最后一天 $date = date('Y-m-d'); function getNextMonthDays($date){ $timestamp=strtotime($date); $arr=getdate($timestamp); if($arr == 12){ $year=$arr +1; $month=$arr -11; $firstday=$year.'-0'.$month.'-01'; $lastday=date('Y-m-d',strtotime("$firstday +1 month -1 day")); }else{ $firstday=date('Y-m-01',strtotime(date('Y',$timestamp).'-'.(date('m',$timestamp)+1).'-01')); $lastday=date('Y-m-d',strtotime("$firstday +1 month -1 day")); } return array($firstday,$lastday); } 二、计算指定时间和当前时间相差年月日时分秒 date_default_timezone_set('PRC');//声明时区 $enddate="2018-6-14 17:29:10"; $date=floor((strtotime($enddate)-strtotime(date('Y-m-d H:i:s')))/86400); echo "相差天数：".$date."天<br/><br/>"; $hour=floor((strtotime($enddate)-strtotime(date('Y-m-d H:i:s')))%86400/3600); echo "相差小时数：".$hour."小时<br/><br/>"; $minute=floor((strtotime($enddate)-strtotime(date('Y-m-d

背景说明 小白：伟哥，java中的set是无序的，Redis中可以带顺序吗？ 伟哥：可以， 不过不叫set了，叫zset。 概述 SortedSet又叫zset，它是Redis提供的特殊数据类型，是一种特殊的set类型，继承了set不可重复的特点，并在set基础上为每个值添加一个分数，用来实现值的有序排列。 redis中排行榜中的数据 public function execute(string $date) { $query = ChannelConfig::query(); $query->where('module_name', 'rank_reward'); $rewardData = $query->first(); $rewards = ; if( $rewardData ){ $rewardContents = $rewardData->content; foreach ($rewardContents as $key => $value) { if( !key_exists($value, $rewards) ){ $rewards] = ; } $rewards]] = $value; } } echo json_encode($rewards); $redisFactory = ApplicationContext::getContainer()->get(RedisFactory::class); $redis = $redisFactory->get('rank'); $day = substr($date,5,2).substr($date,8,2); $keys = $redis->keys("RANK:*:$day:0-0"); foreach ($keys as $key => $value) { // echo "key = $value \n"; $kuCuns = $redis->ZREVRANGE($value, 0, 29, true); // echo "data = ".json_encode($kuCuns)."\n"; $gameType = explode(":",$value); $count = count($kuCuns); $index = 1; foreach ($kuCuns as $keyItem => $valueItem) { $mode = new RankLog(); $mode->date = $date; $mode->index = $index; $mode->gameType = $gameType; $mode->userId = $keyItem; $mode->score = $valueItem; $mode->reward = key_exists($gameType, $rewards) ? $rewards : ""; $mode->save(); $index++; } } } 转自：https://zhuanlan.zhihu.com/p/629389490
