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

while (list($k, $v) = each($array)){
if (...) unset($array[$k]);
}
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]);
}
in short: yes.
you can unset() in this way till the cows come home and
not suffer undue consequences.
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.
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. :-)
if while/list/each & foreach were women, while/list/each would be selling
fish on a market stall & foreach would be having her feet massaged while drinking
dry martini at 35,000 feet :-)
but I guess it's not the done thing to call a language construct sexy ;-)
