// 示例代码：使用PDO防止SQL注入
$pdo = new PDO('mysql:host=localhost;dbname=furniture', 'username', 'password');
$stmt = $pdo->prepare('SELECT * FROM products WHERE id = :id');
$stmt->bindParam(':id', $productId, PDO::PARAM_INT);
$stmt->execute();
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);

// 示例代码：使用Redis缓存
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

if ($redis->get('product_' . $productId)) {
    $product = json_decode($redis->get('product_' . $productId), true);
} else {
    $pdo = new PDO('mysql:host=localhost;dbname=furniture', 'username', 'password');
    $stmt = $pdo->prepare('SELECT * FROM products WHERE id = :id');
    $stmt->bindParam(':id', $productId, PDO::PARAM_INT);
    $stmt->execute();
    $product = $stmt->fetch(PDO::FETCH_ASSOC);
    $redis->setex('product_' . $productId, 3600, json_encode($product));
