上传使用PHP

我上传从我自己的服务器上的文件，以soundcloud.com在PHP中使用的API文件：上传使用PHP

if (isset($mime)) { 
     $tmp_file = $tmp_path . $_FILES['file']['name']; 

     // Store the track temporary. 
     if (move_uploaded_file($_FILES['file']['tmp_name'], $tmp_file)) { 
      $post_data = array(
       'track[title]' => stripslashes($_POST['title']), 
       'track[asset_data]' => realpath($tmp_file), 
       'track[sharing]' => 'private' 
      ); 

      if ($response = $soundcloud->upload_track($post_data, $mime)) { 
       $response = new SimpleXMLElement($response); 
       $response = get_object_vars($response); 
       $message = 'Success! <a href="' . $response['permalink-url'] . '">Your track</a> has been uploaded!'; 

       // Delete the temporary file. 
       unlink(realpath($tmp_file)); 
      } else { 
       $message = 'Something went wrong while talking to SoundCloud, please try again.'; 
      } 
     } else { 
      $message = 'Couldn\'t move file, make sure the temporary path is writable by the server.'; 
     } 
    } else { 
     $message = 'SoundCloud support .mp3, .aiff, .wav, .flac, .aac, and .ogg files. Please select a different file.'; 
    } 
}

这是我的代码。临时路径是http://122.166.23.38/dev3/bids4less/funkeymusic/upload 并且它具有权限777（-rwxrwxrwx）。

但它显示：
