 public static function Convertdatetolong ($DATESTR) {$checkPattern = "/^\d{4} (((-\d {.}) {2}) | ((\.\d{1,2}) {2}) | ((\/\d{1,2}) {2}))        $/"; $date = substr (Trim ($DATESTR), 0,strpos (Trim ($DATESTR), "") >0?        Strpos (Trim ($DATESTR), ""): strlen (Trim ($DATESTR))); if (Preg_match ($checkPattern, $date)) {Preg_match ("/([-\/.])            /", $date, $outer);            $dilimeter = $outer [1];            List ($year, $month, $day) = Explode ($dilimeter, $date);                if (Checkdate ($month, $day, $year)) {$spsec = time ()-mktime (0,0,0, $month, $day, $year);                if ($spsec < 0) throw new Exception ("date can not is after today!!!");                $spday = Floor ($spsec/24/60/60);            return $spday;            } else{throw new Exception ("The date input is not a valid date");        }} else{throw new Exception ("The DATESTR is wrong formatted!!!"); }    }

Leave the validity test aside, this code bend too big. Count days as long as one code:
$day =floor ((Time ()-strtotime ($date))/86400);

Furthermore, the Strtotime supported date format is rich and learning.
