function is_valid_date($datestring) {
if (date('Y-m-d', strtotime($datestring)) == $datestring) {
return true;
} else {
return false;
}
}
Usage examples:
is_valid_date('2005-05-22'); // returns true
is_valid_date('2005-05-32'); // returns false
The function assumes leading zeros are mandatory. If they
are not, here's a revision that will fix it:
function is_valid_date($datestring) {
list($y, $m, $d) = explode('-', $datestring);
list($yy, $mm, $dd) = explode('-', date('Y-m-d',
strtotime($datestring)));
if (($y == $yy) and ($m == $mm) and ($d == $dd)) {
return true;
} else {
return false;
}
}
Cheers,
