// 示例代码：处理表单提交
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $data = $_POST;
    // 连接数据库
    $db = new PDO('mysql:host=localhost;dbname=phpcms', 'username', 'password');
    // 插入数据
    $stmt = $db->prepare("INSERT INTO forms (name, email, message) VALUES (:name, :email, :message)");
    $stmt->bindParam(':name', $data['name']);
    $stmt->bindParam(':email', $data['email']);
    $stmt->bindParam(':message', $data['message']);
    $stmt->execute();
}

// 示例代码：生成验证码
session_start();
$code = rand(1000, 9999);
$_SESSION['captcha'] = $code;

$image = imagecreatetruecolor(100, 30);
$bgColor = imagecolorallocate($image, 255, 255, 255);
$textColor = imagecolorallocate($image, 0, 0, 0);
imagefilledrectangle($image, 0, 0, 100, 30, $bgColor);
imagestring($image, 5, 30, 8, $code, $textColor);
header('Content-type: image/png');
