Yes, there's no need to additionally use urlencode() here. It's just the
wrong function for this purpose. If you want to be absolutely sure that
no one accesses files outside the upload directory, you can additionally
use realpath() after building the path and check if the left part of the
absolute path matches the upload directory, but this shouldn't be
necessary if there are no symlinks or something similar in the
directories referencing files outside.
