The function of phil@philmo contains a few errors...
I corrected them as far as I found them and tried to improve the code.
<?php
/**
* Checks for a valid date
*
* @param string Date in the format "MM-DD-YYYY"
* @param integer Disallow years more than $yearepsilon from now (in future as well as in past)
* @return array [ month, day, year ]
* @since 1.0
*/
/* fixed:
** - leap years
** - december now is allowed
** - removed unnecessary checking
** if you find any more mistakes, please correct them. :)
*/
function datecheck($date, $yearepsilon=5000) {
if (count($datebits=explode('-',$date))!=3) return false;
$month = intval($datebits[0]);
$day = intval($datebits[1]);
$year = intval($datebits[2]);
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)))) return false; // date out of range
return array(
'year' => $year,
'month' => $month,
'day' => $day
);
}
?>
