note 65291 added to function.checkdate

Slightly modified so you don't have to specify a format string. Returns false if the date's invalid; this checks for dd/mm/yyyy first, but to check for eg. mm/dd/yyyy just swap round the $forms array. function datecheck($date, $yearepsilon=5000) { $forms = array('dmy', 'mdy', 'ydm', 'dym', 'myd', 'ymd'); foreach ($forms as $form) { $date=str_replace("/", "-", $date); $form = strtolower($form); if (count($datebits=explode('-',$date))!=3) return false; $year = intval($datebits[strpos($form, 'y')]); $month = intval($datebits[strpos($form, 'm')]); $day = intval($datebits[strpos($form, 'd')]); if ((abs($year-date('Y'))>$yearepsilon) || // year outside given range ($month<1) || ($month>12) || ($day<1) || (($month==2) && ($day>28+(!($year%4))-(!($year%100))+(!($year%400)))) || ($day>30+(($month>7)^($month&1)))) { // date out of range, so check next format } else { // date is ok, so return it return array( 'year' => $year, 'month' => $month, 'day' => $day ); } } // no date found so... return false; } Nick ---- Server IP: 66.163.161.117 Probable Submitter: 213.218.225.25 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.checkdate.php Edit -- http://master.php.net/note/edit/65291 Del: integrated -- http://master.php.net/note/delete/65291/integrated Del: useless -- http://master.php.net/note/delete/65291/useless Del: bad code -- http://master.php.net/note/delete/65291/bad+code Del: spam -- http://master.php.net/note/delete/65291/spam Del: non-english -- http://master.php.net/note/delete/65291/non-english Del: in docs -- http://master.php.net/note/delete/65291/in+docs Del: other reasons-- http://master.php.net/note/delete/65291 Reject -- http://master.php.net/note/reject/65291 Search -- http://master.php.net/manage/user-notes.php
