Something like the following would probably serve as a basis for inspecting "the magic" of a zip archive, regardless of filename extension. This particular example looks to see if the first 2 bytes are "MZ", but this could be changed to look for "PK", instead...
You might want to be careful doing this for zip files. Java .jar files and OpenOffice documents both use the zip format as a container and have "PK" as their "magic".
