Easiest way to alternate row colors in PHP/HTML?

Question

Here's a PHP example of mine. Can anyone find a shorter/easier way to do this?

<? foreach($posts as $post){?>
    <div class="<?=($c++%2==1)?‘odd’:NULL?>">
        <?=$post?>
    </div>
<? }?>

<style>
    .odd{background-color:red;}
</style>

Examples in other languages would be fun to see as well.

Fundamentally - no. That's about as easy as it gets. You might rewrite it a bit shorter/cleaner, but the idea will be the same. This is how I would write it:

$c = true; // Let's not forget to initialize our variables, shall we?
foreach($posts as $post)
    echo '<div'.(($c = !$c)?' class="odd"':'').">$post</div>";
