If you want to compare two dates just convert to your dates to Unix Time stamp, compare them and you have your result. The code will look something like below,
$exp_date = "2015-10-01";
$todays_date = date("Y-m-d");
$today = strtotime($todays_date);
$expiration_date = strtotime($exp_date);
if ($expiration_date > $today) {
// Yes, this is...
} else {
// Yes, this is...
}
Thanks…
