文件上传/移动临时无法在nginx上工作

所以，我读过这个关于move_uploaded_file（）问题的问题。然而，在我的apache供电的localhost灯堆栈上，它运行得很好。所以我认为这可能是文件系统/路径的问题，而不是代码的问题。

当在本地上传文件到我的网站时，它是有效的。

但当我在QA服务器上（它是nginx驱动的）时，我会得到这个错误：

2012/09/08 15:34:21 [error] 11794#0: *5187 FastCGI sent in stderr: "files not empty
PHP Warning:  move_uploaded_file(/var/www/qa.mysite.com/mysite/app/files/maps-aprilfools.tiff): failed to open stream: No such file or directory in /var/www/qa.mysite.com/mysite/app/models/files.php on line 516
PHP Warning:  move_uploaded_file(): Unable to move '/tmp/phpvdtznP' to '/var/www/qa.mysite.com/mysite/app/files/maps-aprilfools.tiff' in /var/www/qa.mysite.com/mysite/app/models/files.php on line 516" while reading response header from upstream, client: 72.xxx.xxx.xxx, server: qa.mysite.com, request: "POST /projects/3/files HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "qa.mysite.com", referrer: "http://qa.mysite.com/projects/3/files"

这是我为处理上传文件而写的代码：

public function fileUploadToProject( $project_id ) {
    if ($_FILES["upload-file"]["error"] > 0) {
        echo "Error: " . $_FILES["file"]["error"] . "<br />";
    } else {
        $dbSuccess      = false;
        $tmp_name       = $_FILES["upload-file"]["tmp_name"];
        $name           = $_FILES["upload-file"]["name"]; // someFile.ext
        $size           = $_FILES['upload-file']['size']; //size in bytes
        $mime           = $_FILES['upload-file']['type']; //size in bytes
        $destination    = __FILES__.'/'.$name;
        $uploaded       = move_uploaded_file( $tmp_name, $destination );
        // add entry to database.
        /*
         * null because there is no container yet.
         * We're only uploading to local
         */
        $user_container_name = null; 
        $uploaded_by = LoggedInUser::get_user_id();
        /*
         * Set this 1 when we're not dealing with our external fileserver
         */
        $isLocal = 1;
        /*
         * Probably shouldn't do this forever for storage size reasons, but for now its useful.
         */
        $localPath = $destination;
        $task_id = null;
        if( $uploaded ) {
        $dbSuccess = $this->insertFileRefService( $task_id, 
                                                  $project_id,
                                                  $user_container_name, 
                                                  $name,
                                                  $mime, 
                                                  $size,
                                                  $uploaded_by,
                                                  $isLocal,
                                                  $localPath
                );
            if($dbSuccess) {
                return true;
            } else {
                // should I rollback / delete that file?
                return false;
            }
        } else {
            return false;
        }
    }
}

那么，关于在nginx上将临时文件移动到我的文件系统，我应该知道什么吗？还是你认为这只是一个路径问题？代码问题？

此外，请注意，第516行是这样的：$uploaded = move_uploaded_file( $tmp_name, $destination );
