The code using strtotime   will fail after year 2038   as given in the first answer in this thread  For example try using the following    a date    2040-11-23   echo date  Y-m-t   strtotime  a date      It will give answer as  1970-01-31  So instead of strtotime  DateTime function should be used   Following code will work without Year 2038 problem     d   new DateTime   2040-11-23      echo  d- gt format   Y-m-t

You can find last day of the month several ways  But simply you can do this using PHP strtotime   and date   function I d imagine your final code would look something like this    a date    2009-11-23   echo date  Y-m-t  strtotime  a date      Live Demo  But If you are using PHP    5 2 I strongly suggest you use the new DateTime object  For example like below    a date    2009-11-23    date   new DateTime  a date    date- gt modify  last day of this month    echo  date- gt format  Y-m-d      Live Demo  Also  you can solve this using your own function like below          Last date of a month of a year        param in   date - Integer  Default   Current Month        return Last date of the month and year in yyyy-mm-dd format     function last day of the month  date              month    date  m   strtotime  date         year     date  Y   strtotime  date         result   strtotime    year -  month -01         result   strtotime  -1 second   strtotime   1 month    result         return date  Y-m-d    result       a date    2009-11-23   echo last day of the month  a date
