note 92518 added to function.date

Reply to "seanj" below: Sorry, your code for determining a leap year is wrong. You cannot just do a mod 4 to determine a leap year. "Years that are evenly divisible by 100 are not leap years, unless they are also evenly divisible by 400, in which case they are leap years. For example, 1600 and 2000 were leap years, but 1700, 1800 and 1900 were not." quote from Wikipedia http://en.wikipedia.org/wiki/Leap_year The function "sarmad dot saadi at gmail dot com" wrote is correct and yours in wrong. Alternatively you can you use the function below <?php function isLeapYear($year){ if( (($year%4 === 0) && ($year%100 !== 0)) || ($year%400 === 0) ){ return true; } else{ return false; } } var_dump( isLeapYear(2000) ); //true var_dump( isLeapYear(2004) ); //true var_dump( isLeapYear(2100) ); //false var_dump( isLeapYear(1700) ); //false var_dump( isLeapYear(1800) ); //false var_dump( isLeapYear(1900) ); //false ?> ---- Server IP: 117.104.162.229 Probable Submitter: 137.154.73.31 (proxied: 137.154.73.31) ---- Manual Page -- http://www.php.net/manual/en/function.date.php Edit -- https://master.php.net/note/edit/92518 Del: integrated -- https://master.php.net/note/delete/92518/integrated Del: useless -- https://master.php.net/note/delete/92518/useless Del: bad code -- https://master.php.net/note/delete/92518/bad+code Del: spam -- https://master.php.net/note/delete/92518/spam Del: non-english -- https://master.php.net/note/delete/92518/non-english Del: in docs -- https://master.php.net/note/delete/92518/in+docs Del: other reasons-- https://master.php.net/note/delete/92518 Reject -- https://master.php.net/note/reject/92518 Search -- https://master.php.net/manage/user-notes.php
