Php 使用zend框架上传图像

我是zend框架的新手。我需要创建一个图像上传用户注册。我已经做到了。我的注册控制器和上传控制器工作。目前，所有图像都正在上载到公用文件夹中的

uploads/user images/

。但我的实际需求是，我必须根据每个用户的用户ID为他们创建一个特定的文件夹，并需要将他们的照片上传到该文件夹。此外，我还需要将该图像路径存储在DB中，作为

实际名称\u当前时间戳\u宽度\u高度.扩展名

，但我不知道如何执行此操作。我在这里包括我的控制器代码：

<?php
/**
 * PhotoController class file
 *
 * This file contains a class for PhotoController
 *
 * @category Zend
 * @package Zend_Controller
 *
 */

class PhotoController extends Daddara_Controller_BaseController
{
    public $session;

    function init()
    {
        parent::init();
        $this->view->headScript()->appendFile('/resources/js/upload.js');
        $this->view->headScript()->appendFile('/resources/js/jquery.min.js');
        $this->view->headScript()->appendFile('/resources/js/jquery.wallform.js');
        $this->view->headScript()->appendFile('/resources/js/modernizr.custom.js');
    //  $this->view->headScript()->appendFile('/resources/js/lightbox/jquery-1.10.2.min.js');
    //  $this->view->headScript()->appendFile('/resources/js/lightbox/lightbox-2.6.min.js');
    }

您可以使用以下命令创建文件夹：

您可以使用和移动文件：

我已经尝试过下面的代码，这对我很有用。现在，我可以根据每个用户的用户id将图像上载到特定文件夹。希望这对其他人有所帮助：-）

这可能会有帮助：@v.eigler:非常感谢您的帮助..但该链接不包含我要求的任何必要信息..当我尝试使用此链接时，它将通知显示为未定义变量：userdir。。实际上，我在$userId中获取用户id，如果该目录不存在，我需要使用它来创建该目录，并且需要将该用户照片存储在此目录中，并在db中存储指向该图像的链接。您可以将变量名称更改为首选名称。但是如果您在实现解决方案时遇到问题，您应该阅读更多的php和zend framework教程。谢谢..我已经给出了一些类似的东西，我不知道这种方法是否正确。。其显示mkdir（）权限被拒绝$userId=$em->getRepository（“Models\User”）->findOneBy（array（'id'=>$this->currentUser->id））；$user_path='$path.$userId'；如果（！file_存在（$user_path））mkdir（$user_path）；
if(mkdir(APPLICATION_PATH . '/public/uploads/' . $userId)){
   //dir created

}

if(copy(APPLICATION_PATH . '/public/uploads/' .$filename, 
   APPLICATION_PATH . '/public/uploads/' .$userId .'/' .$newfilename)) {
  unlink(APPLICATION_PATH . '/public/uploads/' . $filename);
}

            $path = "uploads/user-images/";

            $em = $this->getEntityManager();

            //User Id
            $userId = $em->getRepository("Models\User")->findOneBy(array('id' => $this->currentUser->id));

            $user_path = "$path".$userId->getId()."/";

            if (!file_exists($user_path)) mkdir($user_path, 0777);
