I don't know what I was on when I wrote the previous post!
In php you cannot create static class variables in this way (doh) or at
least I never have managed. So when faced the this problem I replace
what in C++ would be a class variable with a class function
comme ca:
class MyClass
{
function MyVar($val = null)
{
static $datum;
if(is_null($val))
{
return $datum;
}
$dataum=$val;
}
}
I definitely need more coffee!

Larry,
I have hit similar global names space issues in the past and it is a
pain in the behind!
One remedial method that can get it stable enough to start to work on is
to stick the whole messy lot into classes (NOT OBJECTS!) and then the
global name space becomes the local namespace (ie $MyVar becomes
$GarbageCode::MyVar).
Once you have done this, you can put accessors functions around the
class local variables. This means that all new code calls the accessors.
$newVar=GarbageCode::GetMyVar();
Thus, if you improve the internal representation of the garbage code,
code outside the old garbage code will no longer be impacted by the change.
From an FN point of view, you are reducing the access to the variable
to a single function point rather than many function points distributed
throughout the code base.

I have my own script that i would like to make more streamlined as it is
becoming very difficult to work with.
That really depends on the nature of the code. I've some code I have
to work with now that is built around dumping all kinds of stuff into
the global namespace, even from functions. If I ever manage convince
the author what an insanely bad idea that is, it will still be hell to
fix because of the way it's built.
Most code probably isn't quite that bad, though. Your code could
already break down into functions quite nicely, or it could be easier
to just start from scratch. No way to tell without seeing the code.
