Bug description:accessing the iterator inside a foreach loop leads to strange
results
Description:
------------
foreach() is supposed to work on a copy of the iternal iterator.
However, manipulating the iterator inside the foreach loop leads to very
strange results.
-> Also try to print the result of current() inside the foreach loop in the
3 use cases provided. You'll see that the iterator is some kind of
manipulated by foreach
Test script:
---------------
$a = range('a','d');
foreach ($a as $v) { }
var_dump(current($a));
$a = range('a','d');
foreach ($a as $v) { current($a); }
var_dump(current($a));
$a = range('a','d');
foreach ($a as &$v) { current($a); }
var_dump(current($a));
Expected result:
----------------
'a'
'a'
'a'
Actual result:
--------------
false
'b'
false
