Taking the comments of Hightechguy into account, here is a version with variable date formatting:
<?php
/**
* Checks for a valid date
*
* @param string Date in the format given by the format parameter.
* @param integer Disallow years more than $yearepsilon from now (in future as well as in past)
* @param string Formatting string. Has to be one of 'dmy', 'dym',
'mdy', 'myd', 'ydm' or 'ymd'. (Default is 'ymd'
for ISO 8601 compability)
* @return array [ year, month, day ]
* @since 1.0
*/
function datecheck($date, $yearepsilon=5000, $format='ymd') {
$format = strtolower($format);
if (count($datebits=explode('-',$date))!=3) return false;
$year = intval($datebits[strpos($format, 'y')]);
$month = intval($datebits[strpos($format, 'm')]);
$day = intval($datebits[strpos($format, 'd')]);
if ((abs($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)))) return false; // date out of range
return array(
'year' => $year,
'month' => $month,
'day' => $day
);
}
?>
