You can not nest foreach calls.

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
