The simplified example:
Reproduce code:
---------------
<?php
function s() {
static $storage = array(array('x', 'y'));
return $storage[0];
}
foreach (s('a') as $k => $function) {
echo "op1 $k\n";
if ($k == 0) {
foreach (s('a') as $k => $function) {
echo "op2 $k\n";
}
}
}
?>
Expected result:
----------------
op1 0
op2 0
op2 1
op1 1
Actual result:
--------------
op1 0
op2 0
op2 1
The bug is similar to bug #35106 (nested foreach fails when array
variable has a reference), but has different reason.

I thought best is if I provide one script...
<?php
function s($key) {
static $storage = array('a' => array('x', 'y'));
return $storage[$key];
}
function s1($key) {
static $storage = array('a' => array('x', 'y'));
return (array)$storage[$key];
}
function s2() {
static $storage = array('x', 'y');
return $storage;
}
function invoke($op, $st) {
foreach ($st('a') as $k => $function) {
echo "$op $k\n";
$function($op, $st);
}
}
function x($op, $st) {
if ($op == 'op1') invoke('op2', $st);
}
function y() {
}
invoke('op1', 's');
echo "\n";
invoke('op1', 's1');
echo "\n";
invoke('op1', 's2');
?>
You get
op1 0
op2 0
op2 1
op1 0
op2 0
op2 1
op1 1
op1 0
op2 0
op2 1
op1 1
if this is not a bug then why they differ?
