I am developing a smartphone web app that is a game of question answer using jquerymobile API.
when a user click on next button that is a anchor tag then i switch to other page and increment the $_SESSION[‘questionNo’] value. The problem is $_SESSION[‘questionNo’] value increment from 1 to 4 and then again became $_SESSION[‘questionNo’] is 1. why it’s happening i don’t know. Here is my code
<?php session_start();
include("connect.php");
include("header1.php");
$attemp=$_SESSION['questionNo'];
echo $attemp;
$sql = sprintf("select * from question order by pk_id ASC limit %s,%s",$attemp,1);
$result = mysql_query($sql) or die(mysql_error());
$result2=mysql_fetch_array($result);
?>
<div data-role="page" id="group">
<div class="main">
<div id="header2" class="clearfix">
<table border="0" width="100%" id="table">
<tr><td colspan="5"><hr></td></tr>
<tr>
<td colspan="2" id="menu_button1">
<a href="reset.php" rel="external">Reset</a>
</td>
<td align="center">
Score : 50%
</td>
<td> </td>
<td id="menu_button2">
<a href="test.php" rel="external">Next</a>
</td>
</tr>

Use session_start():
