Variable Passing?

Anon

I just installed PHP on my Win2k box, and am having some weird issues...it seems I can't pass a variable from one page to another! I setup a link like

href="test.php?foo=bar"

When I print out the value of $foo, there's nothing there. I also tried a while statement to loop through each $HTTP_POST_VAR, and no variables are present, ever. I installed PHP on a Win2k mchine a couple of weeks ago, and never had an issue like this.

Can someone help?

Okay...when I use THIS script:

while (list ($key, $value) = each ($HTTP_GET_VARS)) {
print "$key: $value<br>";
}

I can get the page to print off:
foo:bar

However, I can't simply use:
print $bar;

Nothing prints! Any ideas?

register_globals is off (this is the default starting with PHP 4.2.0)
