[php] walidacja po typie mime Opcje

[hhg]

piszę walidacje do uploadowanych plikow, i m.in sprawdzam typ mime takiego pliku. Mam wpuszczac tylko .xls, .doc, i pare innych. Niestety cos takiego:

[PHP] pobierz, plaintext 
<?php
if (
			$_FILES[$pointer]['type'] !== 'application/pdf' &&
			$_FILES[$pointer]['type'] !== 'application/msword' &&
			$_FILES[$pointer]['type'] !== 'application/vnd.ms-excel' &&
			$_FILES[$pointer]['type'] !== 'drawing/x-dwf' &&
			$_FILES[$pointer]['type'] !== 'model/vnd.dwf' &&
			$_FILES[$pointer]['type'] !== 'application/acad' &&
			$_FILES[$pointer]['type'] !== 'image/vnd.dwg' &&
			$_FILES[$pointer]['type'] !== 'image/x-dwg'
		) {
			return new Notice(FALSE,'VALIDATE_UPLOADED_WRONG_FILE_FORMAT');
		}
?>
[PHP] pobierz, plaintext 

nie pozwala na jednym kompie wpuścic pliku .xls i .doc a na drugim pozwala!! nie rozumiem dlaczego
czy macie jakies pomysly dlaczego tak się dzieje?

z gory dzieki za pomoc

To z manuala :

$_FILES['userfile']['type']

The mime type of the file, if the browser provided this information. An example would be "image/gif". This mime type is however not checked on the PHP side and therefore don't take its value for granted.

Nie powinno sie brac tego za bardzo wiarygodna informacje o typie mime bo jest ona sprawdzana jedynie po stronie przegladarki a ja mozna oszukac.
Kiedys tez myslalem o walidacji przez typ mime i doszedlem do tego: http://pl2.php.net/manual/pl/ref.fileinfo.php. Niestety nie na kazdym hostingu jest to rozszerzenie :/ A co do typow mime dokumentow to w necie poszperalem troche i znalazlem takie typy:
