// 示例代码：使用Redis缓存域名查询结果
<?php
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

$domain = $_GET['domain'];
if ($redis->get($domain)) {
    echo $redis->get($domain);
} else {
    $result = // 执行数据库查询
    $redis->setex($domain, 3600, $result); // 缓存1小时
    echo $result;
}
?>

// 示例代码：使用预处理语句防止SQL注入
<?php
$conn = new mysqli($servername, $username, $password, $dbname);

$stmt = $conn->prepare("SELECT * FROM domains WHERE domain = ?");
$stmt->bind_param("s", $domain);

$domain = $_GET['domain'];
$stmt->execute();
$result = $stmt->get_result();
?>

// 示例代码：插入域名交易记录
<?php
