1.对题型表的操作
（1）.读取题型表（tb_style)中的数据（read_style.php）：
代码
<?php
//检查数据
/* Connectint,selecting database */
$link=mysql_connect('localhost','root','lizhaoyi')
or die("Could not connect:".mysql_error());
//echo "Connected successfully";
mysql_select_db("db_testsystem") or die("Could not select database");
mysql_query("set names utf8");
$sqlstr="select * from tb_style where sty_select!='0'";
//组合sql
$result=mysql_query($sqlstr,$link);
//执行sql
//跳至窗口页
$row=mysql_fetch_array($result);
if($result){
echo "操作成功！";
echo "$row[0]";
echo "$row[1]";
}else{
echo "操作失败，请重试。";
}
?>
(2).1).添加题型表单(addstyle.html):
代码<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<p align="center"><input type="submit" name="send" value="添加"><input type="reset" name="重设" value="取消"></p>
</form>
</body>
</html>
2).添加题型（add_style.php）：
代码
<?php
//检查数据
/* Connectint,selecting database */
$link=mysql_connect('localhost','root','lizhaoyi')
or die("Could not connect:".mysql_error());
//echo "Connected successfully";
mysql_select_db("db_testsystem") or die("Could not select database");
mysql_query("set names utf8");
$sqlstr="insert into tb_style values('".$_POST['sty_style']."','".$_POST['sty_name']."','0')";
//组合sql
$result=mysql_query($sqlstr,$link);
//执行sql
//跳至窗口页
if($result){
