Empty file name?

Hi!
Im pretty new to this whole thing with PHP and have looked at some examples to learn it.

I currently made a site that for now, runs on WAMP localy.

The thing is, i was wondering if this would be a good code to use on the upload.php site. I get this error when trying to upload a big image file.

It says the filename can not be empty at line 85.

I would appreciate it if anyone had time to look at this for me.

Line 85:

$copied = copy($_FILES['image']['tmp_name'], $newname);

Use below instead of above.

$copied = move_uploaded_file($_FILES['image']['tmp_name'], $newname);
