Bug description: foreach scope modality
Description:
------------
The behaviour of foreach seems to be scope dependent. The following code
(slightly more than 20 lines) should yield the same results in both cases,
but doesn't.
I know that foreach uses the internal array pointer. The result beeing
"de" or "de fr it" is NOT the topic here. The point is that the two
results differ, although the code is the same except for the scope.
This could be the reason for bug #19285
Reproduce code:
---------------
<?php
$usr_langs = array('de', 'fr', 'it');
function f() {
global $usr_langs;
foreach($usr_langs as $lang) {
# do something
}
}
function g() {
global $usr_langs;
foreach ($usr_langs as $lang) {
f();
echo "$lang ";
}
}
echo "Test1:<br>";
g();
echo "<br>----------<br>";
echo "Test2:<br>";
foreach ($usr_langs as $lang) {
f();
echo "$lang ";
}
?>
Expected result:
----------------
Test1:
de
----------
Test2:
de
OR even better
Test1:
de fr it
----------
Test2:
de fr it
Actual result:
--------------
Test1:
de
----------
Test2:
de fr it
