function bug() { $a["a"]="1"; $a["b"]="2"; $a["c"]="3"; /*>>>*/ unset($a["b"]);
for (reset($a);current($a);next($a)) print current($a); }
Previous function outputs only "1" but IMHO should "13".
Note - { print $a["c"]; } still outputs "3"!

P.S.: Current version is still pretty buggy - SEGV quite often but only randomly. :-(

Compiled with apache-1.2.5-ssl and Postgres95.

Unsetting an array element doesn't completely erase it.
I'll fix next() so that it works properly, but that loop
is bad anyway, as it doesn't handle arrays with empty

count()/each()/next()/prev()/reset()/end() were patched
to walk around this implementation side effect.  Users
should no longer be able to notice it, even though it'll
be fixed the Right Way(tm) on 3.1 only.
