I think you should not focus so much on the file extension, as that is mostly
meaningless if someone wanted to attack your system.
Instead, you could wrap a call to the command line 'file' command, which gives
mostly accurate information about a file. Basically it reads the first few
bytes to see it is what it expected. There is a php wrapper for this, but I
forget what its called just now.
If you do need to just grab a file extension though, you can do it with a call
to pathinfo() with the 2nd argument of PATHINFO_EXTENSION.
