題庫，對於教育機構，學校，在線教育，是頗有必要的，網上也有很多的第三方在線題庫系統，可是本次案例，會讓有須要的人瞭解題庫的開發思路，其實很簡單，無非就是一個表單驗證，數據庫驗證。php

一、先構建表單數據
二、把表單數據經過get或者post方式提交到表單驗證頁面，和數據庫進行匹配
三、返回結果，答案正確或者錯誤css

構建表單：
index.phphtml

表單接收
check.phpmysql

//鏈接數據庫
$con = mysql_connect($host,$username,$password);

$username="帳號";
$password="密碼";
$db="數據庫名";
$tb = "表名";
