类似于驾校考试的考试系统
使用到的是数据库表名为：
yhks（用户考试）表，yhkstm（用户考试题目）表，kemu（科目）表，shititimu(试题题目)表，xuanxiang(选项)表，timu(题目)表，shiti(试题)表
实现的功能：
1.进入考试界面
2.点击确定会进一步的确认以防按错
3.考试界面实现倒计时一次一道题点击确定自动跳转下一题
4.点击交卷并显示答案
代码部分(php代码在test0607)
1.选择考试
1.1选择考试后台代码----xuanzeks.php
<?php
session_start();
include("../init.inc.php");
include("../DBDA.php");
$db = new DBDA();

$sst = "select * from shiti";
$ast = $db->Query($sst);
$smarty->assign("ks",$ast);
$smarty->display("xuanzeks07.html");
1.2选择考试前端html代码-----xuanzeks07.html

2.3考试处理后台-----kaoshicl.php
主要作用是将试题代号，用户名存入session，从数据库中计算考试时间，显示倒计时，点击题目下的确定向yhks表存入数据，考试的前提工作
<?php
session_start();
$st = $_POST["st"];
$_SESSION["st"] = $st;//考试题目代号
$uid = $_SESSION["uid"];
$time = date("Y-m-d H:i:s");
include("../DBDA.php");
$db = new DBDA();
$sql = "select shijian from shiti where code =‘{$st}‘";
$sj = $db->StrQuery($sql);
$sks = "insert into yhks values(‘‘,‘{$st}‘,‘{$uid}‘,0,‘{$time}‘)";
$db->Query($sks,1);
$id = $db->conn->insert_id;
$_SESSION["ksid"] = $id;
if(empty($_SESSION["djs"]))
{
$_SESSION["djs"] = array($sj,00);
}
header("location:kaoshi.php");
2.4倒计时处理页面------daojishi.php
<?php
session_start();
$attr = $_SESSION["djs"];
//var_dump($attr);
$fen = $attr[0];
$miao = $attr[1];
if($miao>0)
{
$miao--;
}
else if($miao==0)
{
$miao = 59;
$fen--;
}
$attr[0] = $fen;
$attr[1] = $miao;
$_SESSION["djs"] = $attr;
echo "{$fen}|{$miao}";
if($miao==0 && $fen==0)
{
echo "交卷";
}
2.5答题过程中点击确定自动跳向下一题，ajax处理页面------dati.php
<?php
session_start();
include("../DBDA.php");
$db = new DBDA();
$ksid = $_SESSION["ksid"];//试题代号
$tmdh = $_POST["tmdh"];
$yhda = $_POST["da"];
$shunxu = $_POST["sx"];
//echo $yhda;
//向数据库添加数据
$spd = "select count(*) from yhkstm where kaoshi=‘{$ksid}‘ and shunxu=‘{$shunxu}‘";//判断是否已经答过题
if($db->StrQuery($spd)==1)
{

$db->Query($sql,1);
}
else
{
$sql = "insert into yhkstm values(‘‘,‘{$ksid}‘,‘{$tmdh}‘,‘‘,‘{$yhda}‘,‘{$shunxu}‘)";
$db->Query($sql,1);
}
//跳向下一题
//根据考试ID找到试题ID
$sstid = "select shiti from yhks where code = ‘{$ksid}‘";
$stid = $db->StrQuery($sstid);
//根据试题ID，和顺序找下一个题目
$shunxu++;
$sxyt = "select * from shititimu where shiti = ‘{$stid}‘ and shunxu=‘{$shunxu}‘";
$axyt = $db->Query($sxyt);
$stmmc = "select name from timu where code = ‘{$axyt[0][2]}‘";
$tmmc = $db->StrQuery($stmmc);
$sxx = "select * from xuanxiang where timu=‘{$axyt[0][2]}‘";
$axx = $db->Query($sxx);
$attr = array("shunxu"=>$axyt[0][3],"tmdh"=>$axyt[0][2],"tmmc"=>$tmmc,"xuanxiang"=>$axx);
echo json_encode($attr);
//var_dump($attr);
2.6点击尾部图标自动跳转题目，ajax处理页面------xuanzetm.php
<?php
session_start();
include("../DBDA.php");
$db = new DBDA();
$tmdh = $_POST["tmdh"];
$shunxu = $_POST["sx"];
$ksid = $_SESSION["ksid"];//
//根据考试ID找到试题ID
$sstid = "select shiti from yhks where code=‘{$ksid}‘";
$stid = $db->StrQuery($sstid);
//根据试题ID，和顺序找下一个题目
$sxyt = "select * from shititimu where shiti = ‘{$stid}‘ and shunxu=‘{$shunxu}‘";
$axyt = $db->Query($sxyt);
$stmmc = "select name from timu where code = ‘{$axyt[0][2]}‘";
$tmmc = $db->StrQuery($stmmc);
$sxx = "select * from xuanxiang where timu=‘{$axyt[0][2]}‘";
$axx = $db->Query($sxx);
$attr = array("shunxu"=>$axyt[0][3],"tmdh"=>$axyt[0][2],"tmmc"=>$tmmc,"xuanxiang"=>$axx);
echo json_encode($attr);
2.7点击交卷并显示所考的分数------jiaojuan.php
<?php
session_start();
include("../DBDA.php");
$db = new DBDA();
$ksid = $_SESSION["ksid"];
$uid = $_SESSION["uid"];
$sks = "select * from yhks where code =‘{$ksid}‘";
$aks = $db->Query($sks);
//查看分值
$sfz = "select fenzhi from shiti where code = ‘{$aks[0][1]}‘";
$fz = $db->StrQuery($sfz);
$zf = 0;//开始总分
$sda = "select * from yhkstm where kaoshi=‘{$ksid}‘";
$ada = $db->Query($sda);
foreach($ada as $v)
{
$v[2];//题目
$v[4];//答案
$szq = "select daan from timu where code =‘{$v[2]}‘";
$zqda = $db->StrQuery($szq);//正确答案
if($v[4]==$zqda)
{
$zf = $zf + $fz;
}
}
$sxg = "update yhks set fenshu = ‘{$zf}‘ where code = ‘{$ksid}‘";
$db->Query($sxg,1);
echo $zf;
