New Comment:
You are using the same array in nested foreach() loops.
Apparently the array pointer is moved is the parent loop, which affect
the nested one.
No bug here.

function storage() {
static $storage = array('x', 'y');
return $storage;
}

Description:
------------
foreach changes the array pointer of a static in another function.
Reproduce code:
---------------
<?php
function storage($key) {
// uncomment the following line to see the expected result
// return array('x', 'y');
static $storage = array('a' => array('x', 'y'));
return $storage[$key];
}
function invoke($op) {
foreach (storage('a') as $k => $function) {
echo "$op $k\n";
$function($op);
}
}
function x($op) {
if ($op == 'op1') invoke('op2');
}
function y() {
}
invoke('op1');
Expected result:
----------------
op1 0
op2 0
op2 1
op1 1
Actual result:
--------------
op1 0
op2 0
op2 1
