PHP上传脚本

使用此上传脚本，它在一周前运行良好，但是当我今天检查它时，它失败。我已经检查过该文件夹的编辑特权，它被设置为777，所以不要认为这是问题。任何人都知道问题是什么？PHP上传脚本

这是错误

Warning: move_uploaded_file() [function.move-uploaded-file]: 
Unable to access replays/1275389246.ruse in

我的剧本是

谁承载它？你完全控制了环境吗？或者它是一个可以禁用此功能的网络托管公司？ – anddoutoi 2010-06-01 11:26:36

其在webhotel上，所以我没有完全控制服务器设置，但我做了测试脚本上传小图像文件在同一台服务器上，我没有让他们工作得很好。 – Darkmage 2010-06-01 11:36:49

假设“重播”目录中的文档根目录，确实如果更换该行警告仍然存在：

$target = "replays/";

这个：

$target = $_SERVER['DOCUMENT_ROOT']."replays/";

？

你让我的一天:)添加$ _SERVER ['DOCUMENT_ROOT']。“/ playback /”;并且一切都很好 – Darkmage 2010-06-01 12:22:01

很高兴提供帮助，这也突出了我们必须注意$ _SERVER ['DOCUMENT_ROOT']环境变量中尾随斜线的存在 – 2010-06-01 12:41:20
