Example 2: ajax call to load a page on scrolling

<div class="container">

<?php

 include "config.php";

 // counting total number of posts
 $allcount_query = "SELECT count(*) as allcount FROM posts";
 $allcount_result = mysqli_query($con,$allcount_query);
 $allcount_fetch = mysqli_fetch_array($allcount_result);
 $allcount = $allcount_fetch['allcount'];

 // select first 3 posts
 $query = "select * from posts order by id asc limit 0,$rowperpage ";
 $result = mysqli_query($con,$query);

 while($row = mysqli_fetch_array($result)){

   $id = $row['id'];
   $title = $row['title'];
   $content = $row['description'];
   $shortcontent = substr($content, 0, 160)."...";
   $link = $row['link'];
