switch is case-sensitive, the suffix in the config file is not. Don't
you need a strtoupper() on $last?

You seem to be assuming that nobody is setting upload_max_filesize to
an invalid value, or that if they do, PHP will somehow sanitize it so
that it fits one of those cases. Is that the case? What happens if
you set upload_max_filesize to "jagdajgadk" or '<span
onload="alert(\'Evil!\')"></span>' or something? If this
does work,
you should add a comment that testing indicates that PHP seems to
guarantee that a value in this form is passed.
