php获取本年、本月、本周时间戳和日期格式的实例代码
时间戳格式:
?1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | //获取今日开始时间戳和结束时间戳 $beginToday = mktime (0,0,0, date ( 'm' ), date ( 'd' ), date ( 'Y' )); $endToday = mktime (0,0,0, date ( 'm' ), date ( 'd' )+1, date ( 'Y' ))-1; //获取昨日起始时间戳和结束时间戳 $beginYesterday = mktime (0,0,0, date ( 'm' ), date ( 'd' )-1, date ( 'Y' )); $endYesterday = mktime (0,0,0, date ( 'm' ), date ( 'd' ), date ( 'Y' ))-1; //获取本周起始时间戳和结束时间戳 $beginThisweek = mktime (0,0,0, date ( 'm' ), date ( 'd' )- date ( 'w' )+1, date ( 'y' )); $endThisweek =time(); //获取上周起始时间戳和结束时间戳 $beginLastweek = mktime (0,0,0, date ( 'm' ), date ( 'd' )- date ( 'w' )+1-7, date ( 'Y' )); $endLastweek = mktime (23,59,59, date ( 'm' ), date ( 'd' )- date ( 'w' )+7-7, date ( 'Y' )); //获取本月起始时间戳和结束时间戳 $beginThismonth = mktime (0,0,0, date ( 'm' ),1, date ( 'Y' )); $endThismonth = mktime (23,59,59, date ( 'm' ), date ( 't' ), date ( 'Y' )); //上个月的起始时间: $begin_time = strtotime ( date ( 'Y-m-01 00:00:00' , strtotime ( '-1 month' ))); $end_time = strtotime ( date ( "Y-m-d 23:59:59" , strtotime (- date ( 'd' ). 'day' ))); $begin_year = strtotime ( date ( "Y" ,time()). "-1" . "-1" ); //本年开始 $end_year = strtotime ( date ( "Y" ,time()). "-12" . "-31" ); //本年结束 //现在的时间到第二天凌晨相差的时间戳 $time = ( strtotime ( date ( 'Y-m-d' ))+3600*24) - time() ; |
日期格式:
?1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | //上周起始时间 echo date ( "Y-m-d H:i:s" , mktime (0, 0 , 0, date ( "m" ), date ( "d" )- date ( "w" )+1-7, date ( "Y" ))); echo date ( "Y-m-d H:i:s" , mktime (23,59,59, date ( "m" ), date ( "d" )- date ( "w" )+7-7, date ( "Y" ))); //本周起始时间 echo date ( "Y-m-d H:i:s" , mktime (0, 0 , 0, date ( "m" ), date ( "d" )- date ( "w" )+1, date ( "Y" ))); echo date ( "Y-m-d H:i:s" , mktime (23,59,59, date ( "m" ), date ( "d" )- date ( "w" )+7, date ( "Y" ))); //上月起始时间 echo date ( "Y-m-d H:i:s" , mktime (0, 0 , 0, date ( "m" )-1,1, date ( "Y" ))); echo date ( "Y-m-d H:i:s" , mktime (23,59,59, date ( "m" ) ,0, date ( "Y" ))); //本月起始时间 echo date ( "Y-m-d H:i:s" , mktime (0, 0 , 0, date ( "m" ),1, date ( "Y" ))); echo date ( "Y-m-d H:i:s" , mktime (23,59,59, date ( "m" ), date ( "t" ), date ( "Y" ))); //本年起始时间 echo date (‘Y-01-01'); echo date (‘Y-12-31'); |
获取当月的最后一天和第一天
?1 2 3 4 5 6 7 | $BeginDate = date ( 'Y-m-01' , strtotime ( date ( "Y-m-d" ))); echo $BeginDate ; echo " "; echo date ( 'Y-m-d' , strtotime ( "$BeginDate +1 month -1 day" )); echo " "; |
获取当天年份,月份,以及当月天数
?1 2 3 4 5 6 | echo " 本月共有:" . date ( "t" ). "天" ; echo " 当前年份" . date ( 'Y' ); echo " 当前月份" . date ( 'm' ); echo " 当前几号" . date ( 'd' ); echo " "; |
获取指定月份的天数或者最后一天
?1 2 3 4 5 6 7 8 9 10 | $days = cal_days_in_month(CAL_GREGORIAN, 4, 2011); echo "返回2011-4的天数 " . $days ." "; $days = date ( 't' , strtotime ( "2011-4-1" )); echo "返回2011-4的天数 " . $days ." "; $days = date ( "t" ); echo "当前月的天数 " . $days ." "; cal_days_in_month 的公用:返回某个历法中某年中某月的天数 |
参数介绍:
cal_days_in_month($par1,$par2,$par3);
$par1 :用来计算的某种历法,PHP Calendar 常量
$par2 :参数$par1选中历法中的某个月
$par3: 选中历法中的某一年
返回值:
$par1 选中历法的某年某月的天数
PHP Calendar 常量:日历扩展包含了简化不同日历格式间转换的函数。
为了让这些函数能够工作,您必须通过 --enable-calendar 编译 PHP。window下,已经集成了对日历扩展的支持
案例中的常量CAL_GREGORIAN,是PHP预定义的常量,就像PHP_OS等常量
gregorian 的意思:公历;阳历
