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>';
