Subject: register_globals work arounds
From: lester@lsces.co.uk (Lester Caine)

OK

No discussions on why register_globals has been removed we all understand why 
and now have to live with that ... I'm not winging here!

The question is "Does anybody have an 'elegant' fix to quickly update a legacy 
site that relies on globals to pass variables between page views?"
My original quick thought was simply to remap these variables as 
$_SESSION['var'] so as not to get too deeply into the code base. I've used that 
in a few quick fixes, but I'm not sure that it is acceptable? I have been 
passing the variables via $_REQUEST but that obviously needs a lot more work in 
the html generated, so the session approach would seem better? But needs to 
observe the European rules on use of cookies :(

I'm thinking that what is needed is a sort of PEAR package that would simply be 
added to every page and be provided with a list of variables to manage, so all 
we need to do is scan the site for variables and establish which need to be 
remembered. I've got all sorts of stuff from google/bing searches, but I'm 
obviously not yet asking the right question ;) Has anybody already been down 
that track?
