You can do this...
for( $b=true; <your-statement>; $b = !$b )
{
<your-code>
}
I usually use this solution....
$types = array( 'one', 'two' );
foreach( $list as $item ) # <-- your set of (many) items
{
echo current( $types ); # <-- this prints the current class
# code
next( $types ) or reset( $types ); # and this do the magic
}
Hey! look, this solution can work with more than 2 types...
try it with many types: $types = array( 'one', 'two', three',
'four' );
