記得先去MySQL建立資料庫，裡面要有兩個table：

guess:存放玩家猜過的數字及得到的線索，
要包含id(主鍵編號)、guess(玩家猜的數字)、hint(線索)三個欄位。

create table guess(id integer auto_increment primary key, guess integer, hint char)

rank:存放所有玩家猜的總次數、花費時間：
要包含no(主鍵編號)、name(玩家名稱)、min(花費分鐘數)、sec(花費秒數)、times(猜的總次數)、total(總分，次數+時間)六個欄位。

create table rank(no integer auto_increment primary key, name char, min integer, sec integer, times integer, total float)

一樣要有連接資料庫檔案db.php

<?php
$db = mysqli_connect("localhost", "換成你的MySQL用戶名", "換成你的密碼", "資料庫名稱") or die(mysqli_error());

進入遊戲，輸入玩家名稱畫面長這樣

index.php


<?php
session_start();
include 'style.html';
include 'db.php';
//把上一位玩家的猜數字紀錄清空
$sql1 = "truncate guess;";
mysqli_query($db, $sql1);
//把上一位玩家的筆記也清空
$_SESSION = array();
?>

輸入名稱後就會進入main.php
也就是遊戲主畫面的檔案，每次猜一組新數字都會刷新一次頁面。
一進入遊戲主畫面的時候看到的是這個畫面：

送出第一個答案，有了猜過的紀錄後，輸入答案那塊會往左移，右邊會出現猜過得紀錄：

main.php


<?php
session_start();
include 'style.html';
include 'judge.php';
if (!$_SESSION["name"]) {
	$name = $_SESSION["name"] = $_POST["name"];
}

    <h1

        Number Guessing

    <div class="rule ">
        <p>規則：猜四位數字，範圍介於0~9（可重複）</p>
        <p>數字與位置正確為A，數字正確但位置不正確則為B</p>
        <p>Ex. 正解為1341，猜1354則會得到線索2A1B</p>

筆記區只是方便玩家將確定有的或確定沒有的數字，或確定的位數記錄在上面而已，也可以整塊拿掉不放。

不過因為每次送出所猜的數字都會刷新一次頁面，為了讓玩家所做的筆記在每次刷新頁面後仍能保存起來，
要用session來記下剛剛所作的筆記。
