phpゼリービーンゲーム - 不正確なシーケンシング

Question

誰かが助けてくれますか、私のゲームは正しくシーケンスされていません。どこでもエコーラインxがありますので、シーケンスを見ることができます。この時点では、推測形式（2番目のシーケンス）から最初のフォーム（ゲームの制限を設定する）にジャンプします。ただ、一目

Answer 1

..あなたがsession_start();がそのように、あなたの$ _SESSIONは、ページがロード間で記憶されて追加する必要があります

。

注：すべてのサーバで必ずしも有効になっているとは限りませんので、ではなく、最初の行に完全なphpタグ<?phpを使用してください。

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