note 35772 added to function.checkdate

A validity enhancement to the previous note using is_numeric in addition to checkdate: Since the checkdate function has a bug in it (bug #25530), I think you should be checking for is_int() instead of is_numeric(), at least before the bug is fixed. // Example 1 $day = "4e4"; $mon = "5"; $year = "2000"; if (is_numeric($day) && is_numeric($mon) && is_numeric($year) && checkdate( $mon, $day, $year )) { echo "Valid 1"; } // Result: prints 'Valid 1' // Example 2 if (is_int($day) && is_int($mon) && is_int($year) && checkdate( $mon, $day, $year )) { echo "Valid 2"; } // Result: prints nothing I hope you can see the difference. ---- Manual Page -- http://www.php.net/manual/en/function.checkdate.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+35772 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+35772&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+35772&report=yes
