PHP - move_uploaded_file问题

Question

I've used move_uploaded_file successfully in the past, however I'm having an issue with permissions I believe with a new server I'm testing this on. I've created a folder named "uploads" for the uploads to be moved to via FTP. Here's a screenshot showing the permissions:

Everyone has read/write access, but when I upload a file I'm getting an error on the line that moves the file to the "uploads" directory:

if (move_uploaded_file($_FILES['photo1']['tmp_name'], $upload_directory.$uploadedFile)) {

The file is not moved to the "uploads" folder and looking at the server log I can see entries like this:

php[1344] PHP Warning: move_uploaded_file(uploads/2.jpg): failed to open stream: Permission denied in C:\Program Files\FileMaker\FileMaker Server\HTTPServer\conf\test_upload\index.php on line 206 PHP Warning: move_uploaded_file(): Unable to move 'C:\Windows\Temp\php2D93.tmp' to 'uploads/2.jpg' in C:\Program Files\FileMaker\FileMaker Server\HTTPServer\conf\ test_upload\index.php on line 206

I can't see how it can be a permissions issue if all users have read/write/execute on the "uploads" folder? Here are the variables:

$upload_directory='uploads/'; $uploadedFile= $_FILES['photo1']['name'];

Answer 1

It appears that uploads/2.jpg is $_FILES['photo1']['tmp_name'] and should therefore have been uploaded to the server's /tmp/ directory. On most systems, because /tmp is a system dir, it has restricted permissions on it.

See if you can alter the perms on /tmp or find out exactly which dir the tmp uploaded file is being moved to first, before being "uploaded" (and then alter the perms on that dir).

Regardless, the path to the file as passed to move_uploaded_file() doesn't look right. It needs to be a full-path. Possibly the server-error you're seeing is not happening at precisely the same time as the upload operation takes place.
