A different array question

I've been writing code lately that loops through the $_POST and
$_SESSION arrays and needs to determine if a particular member is a
scalar or an array.

I've found a test that works:

while (list($key, $value) = each($_POST))
{
if ((string) $value == "Array")
etc.

but it really looks a bit tacky to me.

Can anyone suggest something a bit more respectable?

Thanks.

is_array($value)

Also, instead of that while statement why not use the cleaner (looking
at least):

foreach ($_POST as $key=>$value)

Ahh... Thanks! I think I'm beginning to understand...

Because I started PHP towards the end of PHP 3 and I've never got to
grips with the foreach() construct. Is it as easy as it looks? Do
you have to reset() the array afterwards like you do with each()?

Yup, it's that easy, no setting to beginning or resetting afterwards =

needed.
