File::MMagic does that.  I believe someone mentioned a module called 
File::Type also, although I haven't looked at that one.  File::MMagic also 
gives you the option of using a magic file from another source (like the 
file command or Apache)

The trick is that, depending on what magic file you use, it will give you 
either a description or a MIME type - not an extension - so you'll need to 
do your own extension-to-type mapping.  Also, some versions of MS Office 
documents are all identified the same, so you'll have to map the generic 
office types to .doc, .xls, .ppt, etc.
