PHP Get Values from Associative Array

I have a form that collects amounts paid here...

http://buildmomentum.org/register/lc/group_payment.php?id_church=ORG101&total_group_payment=100

When the button is clicked, I need to give the person entering the amounts an opportunity to check their entry.  How do I convert the associative array into variables I can show the user, then pass on to the next page for processing?

I could post code I've tried, but I've tried so many different ways of doing a "For Each" loop and "Implode" from $_POST that I don't know what code to post.  At this point, I think it's easier to start from scratch.

Thanks,

Steve

try:
if(isset($_POST['payment']) && $_POST['payment']=='Confirm totals and make payment.')
{
	foreach($_POST['id_registrant'] as $key=>$value)
	{
		$fieldname=htmlentities($key,ENT_QUOTES,'UTF-8');
		$fieldvalue=intval($value);
		echo sprintf('<div>%s: %d<input type="hidden" name="id_registrant[%s]" value="%d"/></div>',$fieldname,$fieldvalue,$fieldname,$fieldvalue);
	}
}

NOTE: If you were to change the names of your input elements from:
<input type="text" name="id_registrant[lastname63700]" id="id_amount1">

to something like:
<input type="text" name="id_registrant[firstname lastname__63700]" id="id_amount1">

then you could split $key at the double underline to get the first and last names:
if(isset($_POST['payment']) && $_POST['payment']=='Confirm totals and make payment.')
{
	foreach($_POST['id_registrant'] as $key=>$value)
	{
		$temp=explode('__',$key);
		$fullname=htmlentities($temp[0],ENT_QUOTES,'UTF-8');
		$fieldname=htmlentities($key,ENT_QUOTES,'UTF-8');
		$fieldvalue=intval($value);
		echo sprintf('<div>%s: %d<input type="hidden" name="id_registrant[%s]" value="%d"/></div>',$fullname,$fieldvalue,$fieldname,$fieldvalue);
	}
}
