头脑王者php如何实现

<code class="php">class Game
{
    private $questions;
    private $currentQuestion;
    private $score;

    public function __construct()
    {
        $this->questions = $this->loadQuestions();
        $this->currentQuestion = 0;
        $this->score = 0;
    }

    // 其他方法...
}</code>

<code class="php">private function loadQuestions(): array
{
    // 从文件或数据库加载问题
    return [
        [
            'question' => '什么是 PHP 中的超级全局变量？',
            'options' => ['$_GET', '$_POST', '$_SESSION'],
            'answer' => '$_GET',
        ],
        // ...
    ];
}</code>

<code class="php">public function getCurrentQuestion(): array
{
    return $this->questions[$this->currentQuestion];
}</code>

<code class="php">public function checkAnswer(string $answer): bool
{
    $question = $this->getCurrentQuestion();
    if ($answer === $question['answer']) {
        $this->score++;
        return true;
    }

    return false;
}</code>

<code class="php">public function nextQuestion()
{
    $this->currentQuestion++;
}</code>

<code class="php">public function isGameOver(): bool
{
    return $this->currentQuestion >= count($this->questions);
}</code>

<code class="php">public function getScore(): int
{
    return $this->score;
}</code>
