$row = Mysql_fetch_assoc ($query);
$infoid = $row ["Infoid"];
$Title = $row ["Title"];

PHP JSON

You can split the page first and then generate the JSON.

Mister, and then use Json_encode () to generate JSON.
------Solution--------------------
Paging is not in the client with JS, paging is usually on the server side with PHP to calculate the number of database required to obtain, and then directly from the database to obtain the selected records.
For example, you guide the page by the Get or post method,
$page = 1;//First page
$pagenum = 10;//per page
$start = ($page-1) * $PAGENUM;//This is the number of records that are calculated for the start
Your SQL statements can be written like this.
$sql = "SELECT * from AKB ORDER BY infoid desc LIMIT $start, $pagenum";

The front-end part, for example with the jquery library
