Confusing While Loop

On my site, I present:

* coupons for stores
* info about the stores

The coupons run vertically down my page.

The first coupon for each store has a "Show store info" button.

When clicked, the respective store's info appears just below the first coupon.

It looks like this:

* Coupon
* Store Info
* Coupon
* Coupon

I want the "Show store info" button to appear on the last coupon.

And, when clicked, I want the respective store's info to appear after all of the coupons, like this:

* Coupon
* Coupon
* Coupon
* Store Info

The problem is, I can't figure out how to do it. I can only get the store info to appear above all of the coupons, like this:

* Store Info
* Coupon
* Coupon
* Coupon

Can anyone help, please? There must be a way . . .

<?php

if (mysql_num_rows($res) >= 1) 
{



$store = '';



while ($row = mysql_fetch_assoc($res)) 
{



if ($row['store'] != $store)
{

{
echo "</div>";
}



$store = $row['store'];



echo "<div class=\"cpn\">";



// First coupon. Note the "Show store info" button
echo "<table>";

I'll try to explain myself more clearly.

I have a table of coupons. The coupons are in rows. Each row also contains the details of the coupon's store.

Before, I used to echo the coupons one-by-one onto my page, with each coupon's store info appearing beneath it. However, I no longer want to do that, because, if I have multiple coupons for a single store, that store's details appear multiple times on a single page. I am therefore trying to figure out a way to get the coupons for a single store to appear together, with the store's info appearing just once after the last coupon. This means that the last coupon must be the only one to have a "Show store info" button.

So far, the code that I have produced only allows me to echo the store info after the first coupon. The first coupon is also the only one with a "Show store info" button.

How can I echo all of the coupons and make sure that the store info only appears after the last one, which is also the only one to have a "Show store info" button?

 

Here's a better way to explain it.

How can I do the following?

if (last or only coupon with this store ID)

{
echo coupon + "Show store info" button + store info;
}

else

{
echo coupon;
}

I no longer need help with this problem, guys.
