Assuming that the value from your form arrives in the yyyy-mm-dd format leverage the functions PHP supplies for dealing with dates.

date_default_timezone_set('Europe/Bucharest'); 
$datan    = new DateTime($_POST['birthday']);
$rightnow = new DateTime();
$interval = $datan->diff($rightnow,true);
if ($interval->format('%y') > 18) { 
    echo 'Your age is over 18'; 
} else {
    echo 'Your age is below 18!';
}
