One other way to detect a pdf is to just read the first 4 bytes from
the file. Valid pdf files start with "%PDF-". Something similar can be
done with Word docs but I don't know what the magic bytes are. This
approach is pretty similar to what the file command does but is
probably a better approach if you have to support multiple platforms.
