Re: Boolean counter?

[moritz]

You can just use ++ to increment your counter, but when you ask for its value use $counter % 2 instead of the counter itself.

Or if you're not interested in the numeric value 0, but rather that it's a false value, you can also use this update step:

$counter = !$counter;

Or if you do want the numerical value:

$counter = !$counter || 0;
