PHP获取本月起始和截止时间戳

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'));

上月起始和结束,有两种写法:

方法一:

$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

方法二:

$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)
