会话变量不定期增加
[英]session variable not increment regularly
问题描述
I am developing a smartphone web app that is a game of question answer using jquerymobile API. 
我正在开发一个智能手机Web应用程序，该应用程序使用jquerymobile API进行问答游戏。 when a user click on next button that is a anchor tag then i switch to other page and increment the $_SESSION['questionNo'] value. 当用户单击是锚标记的下一个按钮时，我将切换到其他页面并增加$ _SESSION ['questionNo']值。 The problem is $_SESSION['questionNo'] value increment from 1 to 4 and then again became $_SESSION['questionNo'] is 1. why it's happening i don't know. 问题是$ _SESSION ['questionNo']的值从1递增到4，然后又变成$ _SESSION ['questionNo']为1。为什么我不知道它的发生。 Here is my code 这是我的代码
<?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">

Use session_start(): 使用session_start（）：
<?php
session_start();
++$_SESSION['questionNo'];
header('Location:startGame.php');
exit;
?>
