成绩怎么求出来? 高手进来说下思路

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--><?php $strConn="odbc:driver={microsoft access driver (*.mdb)};dbq=".realpath("db.mdb");    $conn = new PDO($strConn);    if($_POST["tj"]=="交卷"){                 //求成绩和                exit();    }    ?>
Copy after login
query('select * from st where id='.$y); $row = $dsn->fetch(); $str=$row['daan']; $q=explode("|",$str); echo ''; echo ''; echo ''; }?>
'; echo $i.'.'.$row['s_name'].'
'; echo ''; echo ''; echo ''; echo '
    '; echo ''; echo '
  • '.$q[0].'
  • '; echo '
  • '.$q[1].'
  • '; echo '
  • '.$q[2].'
  • '; echo '
  • '.$q[3].'


老师要求我们写个考试系统,
  要求:
  1.随即从数据库取8条试题(不可重复)
  2.然后就是求成绩了,(这难到了我)
   
  听说PHP版有很多高手,求思路,求例子

------解决方案--------------------
把题目的id和答题者对该题的答案提交到后台,然后根据id选出正确的答案对比,记录分数求和。
------解决方案--------------------
1.过滤post过来不需要的数据
2.数组和 直接有函数
