PHP Gets the date of last month, next month, month (Strtotime (), date ()), strtotimedate

Write the program today, suddenly found a long time to write a long time to get the number of days of the function, the classic switch version, but to get the number of days last month, I just put the month-1, it was too sleepy, then saw a kind of creepy feeling, would like to deal with again, But I think there is something super convenient way, so found the following version, made a little change.

  Get this month's date:

1 function GetMonth ($date) {2     $firstday = Date ("y-m-01", Strtotime ($date)), 3     $lastday = Date ("y-m-d", Strtotime ("$firstday +1 month-1 Day"); 4     return Array ($firstday, $lastday); 5}

$firstday is the first day of the month, if the year is 2014-2, then the $firstday will be 2014-02-01, then according to the $firstday plus one months is 2014-03-01, another day is 2014-02-28, It's so convenient to use date () and Strtotime ().

  Get last month Date:

1 function getlastmonthdays ($date) {2     $timestamp =strtotime ($date), 3     $firstday =date (' y-m-01 ', Strtotime ( Date (' Y ', $timestamp). ' -'. (Date (' m ', $timestamp)-1). ' -01 ')); 4     $lastday =date (' y-m-d ', Strtotime ("$firstday +1 month-1 Day")), 5     return Array ($firstday, $lastday); 6 }

Last month's date needs to get a timestamp, and then in the month-1 OK, super smart Date () will 2014-0-1 this thing converted into 2013-12-01, too cool.

  Get next month's date:

1 function getnextmonthdays ($date) {2     $timestamp =strtotime ($date), 3     $arr =getdate ($timestamp), 4     if ($ arr[' mon '] = =) {5         $year = $arr [' year '] +1; 6         $month = $arr [' mon '] -11; 7         $firstday = $year. '-0 '. $month. '-01 ' ; 8         $lastday =date (' y-m-d ', Strtotime ("$firstday +1 month-1 Day")), 9     }else{10         $firstday =date (' y-m-01 ', Strtotime (Date (' Y ', $timestamp). ' -'. (Date (' m ', $timestamp) +1). ' -01 ')), one         $lastday =date (' y-m-d ', Strtotime ("$firstday +1 month-1 Day")), and a     }13     return Array ($firstday , $lastday); 14}

The code for the next month's date looks a bit longer because date () doesn't go like this 2014-13-01, it will go straight back to 1970, so we need to deal with the problem of December, except for December the direct month +1 is OK.

Generally speaking, it is very convenient, the date function is too powerful. true techarticle PHP gets last month, next month, this month's date (Strtotime (), date ()), Strtotimedate wrote the program today, suddenly found a long time ago written to get the number of months of the function, the classic ...
