PHP每日禁用/启用按钮[关闭]

Question

I'm creating simple game "Advent calendar" when everyday from 3 of December to 23 of December people will click on current day and can win prizes. All days will be clickable (buttons), so I have problem. I need to make that for example 3 of December people can click only on current (3) day and other days would be disabled. So idea to make that everyday unlocked (enabled) 1 button. How to make that? Possible with timers or etc?

Thank in Advance

<?PHP
$info = getdate();
$date = $info['mday'];

for($i=1;$i<=30;$i++)
{
  if($i==$date)
  {
    echo "<input type='button' value='".$i."' />";
  }
  else
  {
    echo "<input type='button' value='".$i."' disabled />";
  }
  if($i%5==0)
  {
    echo "<br/>";
  }
}

?>
