如何在zend框架中命名上传的文件

use Zend\Http\Request;
use Zend\File\Transfer\Adapter\Http;

$request = new Request();
$files = $request->getFiles();

if (!empty($files['upload'])) {
    $uploadFile = $files['upload'];

    // 获取上传文件的原始名称
    $originalName = $uploadFile['name'];

    // 生成新的文件名
    $newFileName = time() . '_' . uniqid() . '_' . $originalName;

    // 获取文件扩展名
    $extension = pathinfo($originalName, PATHINFO_EXTENSION);

    // 设置上传文件的目标路径
    $destination = '/path/to/upload/directory/';

    // 移动上传的文件
    $adapter = new Http();
    $adapter->setDestination($destination);
    $adapter->addFilter('Rename', array(
        'target' => $destination . $newFileName,
        'overwrite' => true
    ));
    if ($adapter->receive($uploadFile['name'])) {
        // 文件上传成功
        echo '文件上传成功！';
    } else {
        // 文件上传失败
        echo '文件上传失败！';
    }
}
