I do follow the part when it creates a local copy of $GLOBALS.
When it unsets them, is there a subtlety of unset that it ONLY unsets system

Alice,
The big problem here is that you are resetting the $string3 variable in the
loop
for ($j=0; $j<$count_chunk2; $j++) {
$string3= $stringChunk2[$j];// <<<-- resetting
the value
if ($j <$count_chunk_2) {
$string2= " OR ";

You can enable them on a per directory bases with .htaccess, take a look

I recommend using the .htaccess method rather than globally turning on
register globals.

I can't speek about the first problem, but about the second one.
You are not setting the variable $blah as a global variable.
Try this instead
$GLOBALS['blah'] = 'bob';
and that should work.
You need to look into scope when refering to variables and functions.

it is a Linux kernel-level bug if memory is leaking from one process to

You should never use globals. If your function needs a variable, you should
pass it in. There are exceptions to this rule but it's not a good idea to
program normally this way.
