can an array be posted?

Can I use a form to post an array? If so, why doesn't my example work

note that register globals is on....

<form method="post" action="page2.php">
<?php
$allVariablesFromPreviousPage = $_POST;
echo '<input type="hidden" value="',$allVariablesFromPreviousPage,'">';
?>
</form>

....page2.php should now have all the $_POST variables from my page1.php
in the new variable "$allVariablesFromPreviousPage"...but it doesn't.

You could try:

foreach ( $_POST as $postitem ) {
echo '<input type="hidden" name="postitem[]" value="' . $postitem .
'">';
}

Then access the vars from the previous page with
$_POST['postitem']['someitem'].

another approach is to serialize your array, then do a rawurlencode.
Then post it. To retrieve, do a rawurldecode and then unserialize.

this won't work because you've lost your hash index (var name).
You would be left with
$_POST['postitem'][0]
$_POST['postitem'][1]
$_POST['postitem'][2]
$_POST['postitem'][...]
etc.

if you wanted to retain the original var name, you could incorporate it
into the input item's name.

foreach ( $_POST as $varname => $postitem ) {
echo '<input type="hidden" name="page1_'
.$varname.'" value="'.$postitem.'">';
}

Then when pulling it out, you could loop through $_POST and strip out
the 'page1_' prefix if you want.

Yes, but you really don't want to do that, why not store the array on the
server, and retrieve it when the client makes the next request?

I think you can use functions compact->serialize and unserialize->extract
