Description:
------------
I have tried this code in my old server that is working very fine. But after I upgraded my server into Fedora 3 and PHP 5.0.2. that generated the followings error. The server does not allow me to upload the file and say permission denied. But I am very very sure, I have set the correct permission with the dir. The mode of upload_files and its parenet dir are 0777.

Is it a bug of PHP?


Reproduce code:
---------------
	$temp_name = $_FILES['userfile']['tmp_name'];
	$file_name = $_FILES['userfile']['name']; 
	$file_type = $_FILES['userfile']['type']; 
	$file_size = $_FILES['userfile']['size']; 
	$result    = $_FILES['userfile']['error'];
	$file_url  = $upload_url.$file_name;
	$file_path = $upload_dir.$file_name;

	//File Name Check
    if ( $file_name =="") { 
    	$message = "Invalid File Name Specified";
    	return $message;
    }


    $result  =  move_uploaded_file($temp_name, $file_path);


Expected result:
----------------
No Error , the file should be appeared in the dir

Actual result:
--------------
Warning: move_uploaded_file(upload_files/Sunset.jpg) [function.move-uploaded-file]: failed to open stream: Permission denied in /var/www/html/simple_upload.php on line 47
