I feel we're comparing apples with oranges here.
Break; is for breaking out of loops. It shouldn't have anything to do with jumping to somewhere else. Let's say *if* PHP supported jumping through the code. The following should then be two different things:
while (loop) {
goto LABEL;
}
:LABEL
while (loop) {
break;
}
I think the question here is if we want to implement jumping through the code or not. If we do jumping in the code, this should be a full-fledged feature. If not, there should be no jumping. And it should, in my opinion, certainly not change the way break; works.

Exceptions are structured way of handling code flow - you can not get to random points of code with exception, you can get either to enclosing catch or stop the program entirely. Unlike exceptions, goto allows to jump to a random point of code. I don't know what do you mean by "limited" - I see that the consensus among the goto proponents is to not impose any limits on the place you could jump to - because, of course, once you strated to jump around you always can find a use for jumping to any place, if you are creative enough - and I do not doubt creativity of PHP people.
