function countdays($d){ $olddate =
substr($d, 4); $newdate =
date(Y)
."".$olddate; $nextyear =
date(Y)+1 ."".$olddate; if($newdate
> date("Y-m-d")) { $start_ts
= strtotime($newdate); $end_ts
= strtotime(date("Y-m-d")); $diff
= $end_ts -
$start_ts; $n
= round($diff
/ 86400); $return
= substr($n, 1); return
$return; } else { $start_ts
= strtotime($nextyear); $end_ts
= strtotime(date("Y-m-d")); $diff
= $end_ts -
$start_ts; $n
