//PHP server
/*
PHP paging function
function Ajaxpage($sql,$num){
global $db;
$pageno=$_GET['pageno '];
$pageno=(int)$pageno;
if(empty($pageno)||$pageno<1) $pageno=1;
$result=$db->query( $sql);
$number=$db->num_rows($result);
$totalpage=(int)ceil($number/$num);
if($pageno>=$totalpage ){$pageno=$totalpage;}
$start_rowno=($pageno-1)*$num;
$query=$sql." LIMIT ".$start_rowno.",".$num;
$result=$db->query($query);
return array('result'=>$result,'page'=>array('pageno'=>$pageno,'totalpage' =>$totalpage,'number'=>$number));
}

$sql="select * from guest";//Query SQL statement
$num=2; //Paging control, display 2 records per page
$return=Ajaxpage($sql,$num);
while($row=$db->fetch_assoc($return['result'])) {
$result[]=$row; //You can use PHP to process the data here, but I won’t give an example here
}
$result=array('result'=>$result,'page '=>$return['page']);
include('json.class.php');//Include JSON class file
$json=& new Json();
$result =$json->encode($result);//JSON
echo $result;
*/
//If the pageno parameter is sent through AJAX and the resource obtained from the database is $str after JSON Like this, output directly and let JS process it.
//If you don’t understand anything, you can ask me
if(ob_get_length()) ob_clean();
