$length=strlen($counter);
$page_count=ceil($length/5000);
function msubstr($str,$start,$len){
$strlength=$start+$len;
$tmpstr="";
for($i=0;$i<$strlength;$i++) {

';
}
if(ord(substr($str,$i,1))>0xa0) {
$tmpstr.=substr($str,$i,2);

$c=msubstr($counter,0,($page-1)*5000);
$c1=msubstr($counter,0,$page*5000);
