With the date and strtotime functions, you can easily obtain the first and last days of the current month, next month, and last month. The following describes their implementation. The date format of the function is yyyy-MM-dd.

1. specify a date to obtain the first and last days of the month.

The code is as follows:

Function getCurMonthFirstDay ($ date ){
Return date ('Y-m-01 ', strtotime ($ date ));
}

Function getCurMonthLastDay ($ date ){
Return date ('Y-m-D', strtotime (date ('Y-m-01 ', strtotime ($ date).' + 1 month-1 DAY '));
}

2. specify a date to obtain the first and last days of the next month.

The code is as follows:

Function getNextMonthFirstDay ($ date ){
Return date ('Y-m-D', strtotime (date ('Y-m-01 ', strtotime ($ date).' + 1 month '));
}

Function getNextMonthLastDay ($ date ){
Return date ('Y-m-D', strtotime (date ('Y-m-01 ', strtotime ($ date).' + 2 month-1 DAY '));
}

3. specify a date to obtain the first and last days of the next month.

The code is as follows:

Function getPrevMonthFirstDay ($ date ){
Return date ('Y-m-D', strtotime (date ('Y-m-01 ', strtotime ($ date).'-1 month '));
}

Function getPrevMonthLastDay ($ date ){
Return date ('Y-m-D', strtotime (date ('Y-m-01 ', strtotime ($ date).'-1 DAY '));
}

The strtotime function parameter "+ 1 month", php determines the number of days to be added based on the specific month, which may be 28, 29 (February), 30 (small month), or 31 (large month ); the first day of a month, "-1 day", is naturally the last day of the month. php will be intelligently identified as 28, 29, 30, or 31 based on the month.
