I'm not so sure, he is "storing" the data for the purpose.  The purpose 
is to create a "group" of "people" based on certain parameters - and 
then display them to the end user.

So each "generate" function outputs it's object data to the screen - 
thus "Storing" the data in the output.

On the downside, one gotcha with this method of generation is that the 
web page will "generate" a new set of data every time it is loaded - so 
if the end user wants to print the data on the screen depending on the 
browser, it may completely resubmit the request so what is on the screen 
would not be what is printed out.


I think you may want to also throw in some migration to using models and 
views as well - so for example
generate_person: today it creates the stats and displays it

Model/View
generate_person: creates a person and returns the object
print_person: displays the person data

generate_squad: creates a squad object which contains an array of person 
objects
print_squad: displays the squad data


Also, as I'm assuming that this is being done as an exercise in learning 
and fun, you should not use global functions like generate_person, 
generate_squad, etc.

You should either be namespacing your functions so as to get them out of 
the global namespace, ie:
traveller/generate/person
traveller/generate/squad

Or you should look into the Factory pattern 
http://en.wikipedia.org/wiki/Factory_method_pattern for this sort of thing.

And of course, most important, have fun, since that's what PHP 
programming is all about.

Subject: [nycphp-talk] OT: Mailman question
Message-ID: <CAN7=Vv8kPErJ1aPcpH8D5Y4Z=UCE71eAzioLUr2mkZMyCAZdjQ@mail.gmail.com>

I'm helping out a friend. His server had a hardware failure. He has a
backup, and has retrieved the Mailman files for the mailing list he
maintains. The mailman directory he sent me has the following directories
at the top level:

archives  data  lists  spam

His goal is to extract the e-mail addresses of the subscribers so he can
re-invite them to a new mailing list system.

How can I extract the e-mail addresses of the subscribers? I looked around
in the files and unless I missed something there doesn't appear to be a
text file with a list of the e-mail addresses. I'm guessing that I could
install Mailman on my Linux server and do something to extract these e-mail
addresses?

I'd greatly appreciate some helpful suggestions with this. Thanks in
advance!

Yeah, you'll have to have an install of mailman somewhere.  Then you can
use the list_members in mailman's bin directory (i.e. /usr/lib/mailman/bin
if installed from RPMs).
