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.

Answer 1

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>"; 

Answer 2

If you'd like to have less in-line PHP, a great way of doing it is via JavaScript.

Using jQuery, it's simply:

<script type="text/javascript"> $('div:odd').css('background-color', 'red'); </script>
