php 糖豆游戏 - 顺序不正确

Question

谁能帮忙，我的游戏顺序不正确，我到处都有回声线 x，所以我可以看顺序。此时，它从猜测形式（第二个序列）跳到第一个形式（您设置游戏限制的地方）。

<?
//$stage = 1;
//$_SESSION['stage'] = 1;
//if(!$_SESSION['stage']){$_SESSION['stage'] = 1;}
if(!$_SESSION['stage']){$_SESSION['stage'] = $stage;}


/* sequence control
    $_SESSION['stage']++;
    $_SESSION['stage'] = 1;
    echo "stage at" . $_SESSION['stage'];
*/

if($_SESSION['stage'] == 1){
    if(!$_SESSION['r']){
            $_SESSION['stage'] = 1;
            firstForm();
            echo "<p>31</p>";
            //exit();
        }else{
        if($_POST['submit']){
            echo "<p>line 35</p>";
            if($_SESSION['stage'] == 1){
                echo "<p>line 37</p>";
                checkRange();
            }else{echo "<p>line 39</p>";$_SESSION['stage']++;}
        }
        if(!$_POST['submit']){
            echo "<p>42</p>";
            firstForm();
        }
    }
}
if($_SESSION['stage'] >= 2){
    echo "48";
    if(!$_SESSION['r']){
            echo "49 stage at" . $_SESSION['stage'];
            //guessForm();
        }
    if(!$_POST['guess'] && $_POST['submit'] != "guess"){
        echo "<p>line 54</p>";
        if($_SESSION['stage'] == 2){
            echo "<p>line 56</p>";

            guessForm();

            echo "Guess was too high, try again.";
            guessForm();
        }else{
            echo "<h1>Correct Guess! Well done.</h1>";
            echo "<h2>It took you " . $_SESSION['counter'] . " guesses.";
            restartForm();
            $_SESSION['r'] = null;

快速浏览一下..

您需要添加一个 session_start(); 以便在页面加载之间记住您的 $_SESSION。

附带说明：请在第一行使用完整的 php 标签 <?php 而不是 <?，因为它并非总是在所有服务器上启用。

<?php
session_start(); // ** Added
// The Rest of your code //
