Alternating

There are dozens of ways to alternate.  The most common and visible is the background colour of your tabular data.  I use PHP to generate my HTML and the following are my two favourites:

foreach( (array)$results AS $K => $V )

{$alt = ( $alt == ‘odd’ ) ? ‘even’ : ‘odd’ ;}

This works well for in iteration variable.  But, what if you’ve got something declared before this loop and you don’t want to ask for that same declaration over and over.  ( Lack of speed kills. )

$i = 0 ;

foreach( (array)$results AS $K => $V )

{

$alt = ( eregi( “\.” , ( $i / 2 ) )  ) ? ‘even’ : ‘odd’ ;

$i++;
}
