Answer 1

If you are just using these class names for alternating CSS styles there is a much elegant way to do this using CSS3

Your HTML

And in your css file

.span4:nth-child(even) {background: #CCC}
.span4:nth-child(odd) {background: #FFF}

else for a PHP solution the answer by Liam Wiltshire should work good.
