$fdate=F("FDATE");<br>         $endtoday=mktime(0,0,0,date('m'),date('d')+1,date('Y'))-1; <br>         if($fdate['time'] != $endtoday)<br>             {$fdate['time']=$endtoday;<br>              $fdate['code']='1';<br>             }<br>         if($fdate['code']  999)<br>             {$fdate['code']='1';<br>             }<br>                 <br>         $date['orderstatus'] = '1';<br>         $date['orderno'] =date('Ymd').str_pad($fdate['code'],3,"0",STR_PAD_LEFT);<br>         $fdate['code'] =$fdate['code'] + 1;<br>         F("FDATE",$fdate);
