Well, you don't have to take away all the "break;". :)
For example, only here:
> switch ($foo) {
> case 'step2':
> do_step2();
> if ($error) $foo='step1'; //repeat step1
> break;
- E
>
>
>If you don't break, it continues to execute all the code until
>the end of the switch, ignoring any subsequent case
>statements.

>In my example, eliminating the break after step2 would
>cause execution of do_step1(), but also do_something_else(),
>which is not desired.
