Bug description: Foreach uses the same internal pointer in different
iterations of recursive fns
Description:
------------
Sorry if this is not a bug, but I think the behavior is not normal, even
after searching the net and this bug database.
It seems that, used inside a recursive function, foreach doesn't use
different array pointers for each iteration of the function, but uses the
same at each time. This common pointer is reseted at each foreach() call.
Reproduce code:
---------------
function recurse($doRecurse = true) {
static $array = array(1,2);
foreach ($array as $value) {
echo $value . PHP_EOL;
if ($doRecurse) recurse(false);
}
}
recurse();
Expected result:
----------------
1
1

Actual result:
--------------
