Somewhere in the manual (damned if I can find it now) it says (or used

while (list($k, $v) = each($array)){

}
I don't even remember if it's safe or not, but I swear I saw it not
that long ago...
Anyway, can you do *this* safely as a DOCUMENTED FEATURE:
foreach($array as $k => $v){
if (...) unset($array[$k]);
}
I'm sure I could test it and maybe find out if "it works" but is it
documented behaviour I can rely on? I'm sure not finding this in the
manual now that I go looking for it, though I know I saw it there
before.
I would *think* (just my opinion without much thought on a Friday
morning) that this would/could be unsafe _if_ it was a for loop on a
numerical indexed array. Of course, my thinking may change after my
first bottle of Dew. ;)
PS
I'm being dragged kicking and screaming into using this new-fangled
'foreach' thing instead of while/list/each, and I don't really care
for it so far. :-)
For the longest time, I hated foreach. Looked at other people's code
who used it, and just wanted to strangle them. However, I was sorta
forced into it about 8 months ago, and now I'm in the camp of, "Damn, I
really like this".
