vc客户端向php server端post abc.txt文件，但在php server端的upfiles目录下未生成abc.txt文件，用Fiddler抓包，发现php server端返回http 200，post的abc.txt文件内容也有，为啥server收不到呢？请高手指点。非常感谢！
abc.txt文件内容：
verify:local
id:1111
host:2.2.2.2
id:2222
host:3.3.3.3
id:3333
host:4.4.4.4Fiddler抓包截图：php server端代码：
<?php
$uploadfile = "upfiles/". $_FILES['upfile']['name'];
move_uploaded_file($_FILES['upfile']['tmp_name'], $uploadfile);
?>

检查upfiles目录的权限，用户是否有写权限？
