一、本月起始和结束
//获取本月开始的时间戳 $beginThismonth=mktime(0,0,0,date('m'),1,date('Y')); //获取本月结束的时间戳 $endThismonth=mktime(23,59,59,date('m'),date('t'),date('Y'));
二、上月起始和结束
写法一:
$m = date('Y-m-d', mktime(0,0,0,date('m')-1,1,date('Y'))); //上个月的开始日期$t = date('t',strtotime($m)); //上个月共多少天$start = date('Y-m-d', mktime(0,0,0,date('m')-1,1,date('Y'))); //上个月的开始日期$end = date('Y-m-d', mktime(0,0,0,date('m')-1,$t,date('Y'))); //上个月的结束日期//echo 15*24*3600;//echo 30*24*3600;$time=strtotime($start);dump(date('Y-m-d H:i:s',$time));//2017-06-01 00:00:00$jieshu=strtotime($end);dump(date('Y-m-d H:i:s',$jieshu));//2017-06-30 00:00:00
写法二:
$thismonth = date('m');$thisyear = date('Y');if ($thismonth == 1) {$lastmonth = 12;$lastyear = $thisyear - 1;} else {$lastmonth = $thismonth - 1;$lastyear = $thisyear;}$lastStartDay = $lastyear . '-' . $lastmonth . '-1';$lastEndDay = $lastyear . '-' . $lastmonth . '-' . date('t', strtotime($lastStartDay));$b_time = strtotime($lastStartDay);//上个月的月初时间戳$e_time = strtotime($lastEndDay);//上个月的月末时间戳2017-06-30 00:00:00(注意 是最后一天的开始时间点)
