Not that I see how exceptions came into the discussion, but anyway.
I have small example of "code" that would be so much easier to
understand and follow with goto..
I removed all actual code to make it a bit shorter, it's actually
around 150-200 lines long, just this outer for-loop..
for (...; ...; ...) {
if (...) {
... code ...
for (...; ...; ...) {
if (...) {
if (...) {
... code ...
continue 2;
} else {
... code ...
break;
}
} elseif (...) {
... code ...
break;
} else {
if (...) {
... code...
}
... code ..
}
}
if (...) {
... code ...
} else {
... code ...
}
} else {
.... code ...
}
}
I have two more like that one..
First a main one, the one above is in a function and the other one in
another function.. They were all part of the same one when I first
made it, but as all the breaks and continues made it impossible to
understand how the code worked, I made the code pass around some vars
instead and break/continue in the main one instead depending on what
the functions return. So if I want to add more stuff I would have to
change breaks and continues in all three anyway, but at least now I
can understand what it does, although I have to read it several times
first and adding some simple thing to it is just a headache.
I actually have to add and change some things in it, but if we are not
going to have goto in PHP I'm just going to rewrite it as a small app
in C which have goto instead and save me hours and hours of headache.
Without exaggerating, I get depressed everytime I look at the code..
I'm sure there are others who have an equal or an even worse mess to
work with.
