A change request just came in - the interaction designer wants every
third line to have a grey background, instead of every second line.
# before was $styles = array( 'even', 'odd' );
# after new requirements it is...
$styles = array( 'white', 'white', 'gray' );
foreach($items as $item)
{
printf( '<li class="%s">%s</li>', current( $styles ), $item );
next( $styles ) or reset( $styles );
}
The simplest solution is always the best choice.
This provides maintainability and flexibility to changes ( that we don't
know yet )
