本文实例讲述了php计算到指定日期还有多少天的方法。分享给大家供大家参考。具体如下：
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;
$n = round($diff / 86400);
$return = substr($n, 1);
return $return;
}
