How to get multiple times using PHP
1. Get the time of the first day and the last day of last month
The first day of last month:
echo date('Y-m-d', strtotime(date('Y-m-01') . ' -1 month'));// 计算出本月第一天再减一个月
The last day of last month:
echo date('Y-m-d', strtotime(date('Y-m-01') . ' -1 day'));// 计算出本月第一天再减一天
2. Get the first and last day of the month
$BeginDate=date('Y-m-01', strtotime(date("Y-m-d"))); echo $BeginDate; echo date('Y-m-d', strtotime("$BeginDate +1 month -1 day"));
3. Get the year, month, day and number of days of the day.
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');
4. Use functions and arrays to get the first and last day of the month, which is more practical:
function getthemonth($date) { $firstday = date('Y-m-01', strtotime($date)); $lastday = date('Y-m-d', strtotime("$firstday +1 month -1 day")); return array($firstday,$lastday); } $today = date("Y-m-d"); $day=getthemonth($today); echo "当月的第一天: ".$day[0]." 当月的最后一天: ".$day[1];
5. Get the date of this month :
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); }
6. Get the date of the previous month:
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); }
To get the date of the previous month, you need to get a timestamp first, and then add -1 to the month. , the super smart date() will convert something like 2018-0-1 into 2017-12-01.
7. Get the date of the next month:
function getNextMonthDays($date){ $timestamp=strtotime($date); $arr=getdate($timestamp); if($arr['mon'] == 12){ $year=$arr['year'] +1; $month=$arr['mon'] -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); }
