Erro com case.

[rfrancisco]

tenho dois códigos em duas divs, na index.php:

<?php
$advertise = rand(1,3);
switch ($advertise) {
        case 1: 
                $banner = "plano1_a.jpg"; 
                $url = "corretor.php?cod=$plano1_a"; 
                $heigth = "200"; 
                $width = "400";
                break;
        case 2: 
                $banner = "plano1_b.jpg"; 
                $url = "corretor.php?cod=$plano1_b"; 
                $heigth = "200"; 
                $width = "400";
                break;
        case 3: 
                $banner = "plano1_c.jpg"; 
                $url = "corretor.php?cod=$plano1_c"; 
                $heigth = "200"; 
                $width = "400";
                break;
}
echo '<a href="'. $url .'"><img src="'. $banner .'" width="'. $width .'" height="'. $heigth .'" alt=""/></a>';
?>

<?
$advertise2 = rand(1,2);
switch ($advertise2) {
        case 1: 
                $banner2 = "plano2_a.jpg"; 
                $url2 = "corretor.php?cod=$plano1_a"; 
                $heigth2 = "200"; 
                $width2 = "400";
                break;
        case 2: 
                $banner2 = "plano2_b.jpg"; 
                $url2 = "corretor.php?cod=$plano1_b"; 
                $heigth2 = "200"; 
                $width2 = "400";
                break;
}
echo '<a href="'. $url2 .'"><img src="'. $banner2 .'" width="'. $width2 .'" height="'. $heigth2 .'" alt=""/></a>';
?>

Não funcionou corretamente, as vezes abre imagens do $advertise um no $advertise2.
