Form variables aren't available with IIS4

[Anon]

I'm using NT server 4.0, IIS 4.0 and PHP4... I have a very simple form, with a text box that is named "foo" and has the value "bar". In my PHP script, I do the following:

echo $HTTP_POST_VARS["foo"];

and it outputs nothing. However, I also have an "echo phpinfo()" call, and it lists HTTP_POST_VARS["foo"] as having the value "bar".

I'm very new to PHP, so it could be a really obvious mistake on my part... (Although the phpinfo() call says that track_vars is on, so that shouldn't be it?). I've looks through the archived messages, and nothing helps...

Any ideas?

TIA,
-Walter.

I'm using the ISAPI library, not the CGI executable... How buggy is the ISAPI library?

Also, I tried doing:

while (list($var, $value) = each($HTTP_POST_VARS)) {
echo "$var = $value<br>\n";
}

and I got the error message:

Warning: Variable passed to each() is not an array or object in
C:\path\default.php on line 15

Something is seriously amiss,

Like I said, I'm really new at this... None of the examples say to put:

global $HTTP_POST_VARS;

somewhere in the code...

You shouldn't have to put that unless you're trying to access it within a function...
