[ciapug] File extension phpm

[Carl Olsen]

I'm reading a book by Wrox, "Professional PHP5" and it uses a file extension
of .phpm for several of the generic class files in Chapter 7.  I briefly
brushed over chapters 1 and 2 and have been reading the rest of the chapters
thoroughly (sometimes several times) and I haven't seen an explanation for
why this file extension is necessary.  My web server isn't configured to
recognize it, but it seems to run just fine as long as it's included in a
page that has the normal .php file extension.  I'm thinking there must be
some kind of security reason for this naming convention, but I can't figure
out what it could be.  Does anyone know what it means?

Another thing is that the first 6 chapters name all their class files with
class.name_of_class.php and all their interfaces with
interface.name_of_interface.php, but the ones with .phpm begin with the name
of the class.  I suppose the .phpm might simply be a way of naming class
files, but the book doesn't explain why these class files are named
differently than the previous examples.
