Re: file upload strange - doesn't appear in filesystem, but can be move_uploaded_file()ed

You should first check by is_uploaded_file() and then move it by
move_uploaded_file(). It is the only safe way with PHP. These
functions goes through bunch of PHP security restrictions instead of
normal file functions.

Until move_uploaded_file() called or request finished file is in temp
dir with temp name. After move or script exit it is deleted.

It only means that you actually do move_uploaded_file() before
is_uploaded_file() somewhere.
