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. [/quote]
Therefore, if you're concerned about users "sneaking" invalid file types in, simply checking the type as above or checking the file name's suffix will not be sufficient. You would actually need to read the header information from the file to determine what type it really is. For image files, this can be done with the[url=http://www.php.net/exif_imagetype]exif_imagetype() function[/url] . I don't know if there's anything similar for .wma files.
