Re: [PHP-DEV] PHP 4.0 Bug #8428 Updated: continue doesn't pass thru a switch statement From: Cynic (cynic <email protected>)
Date: 01/05/01

Forgot to cc the list...

Um, I don't know. This looks to me like trying to hide problems/
inconsistencies/bugs too easily. :) I think it should stay in
the bug realm.

I, just like the other guy, consider this a bug. What good
is continue within switch if it's the same as break, while it's
clearly (meant to be) something different? It could as well
trigger an error: 'use break instead'.
