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 ; } } |
