PHP obtains the date range of the current week (month)

The program needs to write a date range for obtaining the current week, that is, the date range from Monday to Sunday.

Function getWeekRange ($ date ){

$ Ret = array ();

$ Timestamp = strtotime ($ date );

$ W = strftime ('% U', $ timestamp );

$ Ret ['sdate'] = date ('Y-m-d 00:00:00 ', $ timestamp-($ W-1) * 86400 );

$ Ret ['update'] = date ('Y-m-d 23:59:59 ', $ timestamp + (7-$ w) * 86400 );

Return $ ret;

}

// Author: zhxia obtains the start date and end date of the month of the specified date.

Function getMonthRange ($ date ){

$ Ret = array ();

$ Timestamp = strtotime ($ date );

$ Mdays = date ('T', $ timestamp );

$ Ret ['sdate'] = date ('Y-M-1 00:00:00 ', $ timestamp );

$ Ret ['update'] = date ('Y-m-'. $ mdays. '23:59:59', $ timestamp );

Return $ ret;

}

// Author: application of the preceding two functions of zhxia

Function getFilter ($ n ){

$ Ret = array ();

Switch ($ n ){

Case 1: // Yesterday

$ Ret ['sdate'] = date ('Y-m-d 00:00:00 ', strtotime ('-1 Day '));

$ Ret ['update'] = date ('Y-m-d 23:59:59 ', strtotime ('-1 Day '));

Break;

Case 2: // this week

$ Ret = getWeekRange (date ('Y-m-d '));

Break;

Case 3: // last week

$ StrDate = date ('Y-m-d', strtotime ('-1 week '));

$ Ret = getWeekRange ($ strDate );

Break;

Case 4: // last week

$ StrDate = date ('Y-m-d', strtotime ('-2 week '));

$ Ret = getWeekRange ($ strDate );

Break;

Case 5: // this month

$ Ret = getMonthRange (date ('Y-m-d '));

Break;

Case 6: // last month

$ StrDate = date ('Y-m-d', strtotime ('-1 month '));

$ Ret = getMonthRange ($ strDate );

Break;

}

Return $ ret;
