True, css does not allow numeric classes (like sessions). But, I never need them anyway.

As I provided before: http://webbytedd.com/b/color-rows/ this is my solution for alternating row style.

<tr class="row<?php echo($i++ & 1 );?>"> <td >abc</td> <td >abc</td> <td >abc</td> </tr> That's just wasteful... Here's better: <tr class="row<?php echo( $i ^= 1 );?>">

    <td >abc</td>
    <td >abc</td>
    <td >abc</td>

</tr> Cheers, Rob.

wtf? that's some freaky bug right there rob.. <?php for($i=0;$i<10;$i++) { ?> <tr class="row<?php echo( $i ^= 1 ); ?>">

     <td >abc</td>
     <td >abc</td>
     <td >abc</td>

</tr> <?php } ?> output: <tr class="row1">

     <td >abc</td>
     <td >abc</td>
     <td >abc</td>

</tr> <tr class="row3">

     <td >abc</td>
     <td >abc</td>
     <td >abc</td>

</tr> <tr class="row5">

     <td >abc</td>
     <td >abc</td>
     <td >abc</td>

</tr> <tr class="row7">

     <td >abc</td>
     <td >abc</td>
     <td >abc</td>

</tr> <tr class="row9">

     <td >abc</td>
     <td >abc</td>
     <td >abc</td>

</tr> php 5.2.5 - weird

Nooooooo... you introduced the bug, my code presumed a foreach loop and $i intialized to 0. You're code doesn't work with tedd's version either since you're incrementing $i in the loop and in the HTML output... thus it will always be even. Cheers, Rob.

but the rest should echo regardless..? doh scratch that
