Description:
------------
The german and italian translation of the foreach construct with reference variable have shortened the illustrative source code (or are outdated and based on an earlier version).

Reproduce code:
---------------
The incomplete example in the german and italian version is:
<?php
$arr = array(1, 2, 3, 4);
foreach ($arr as &$value) {
    $value = $value * 2;
}
// $arr vale ora array(2, 4, 6, 8)
?>



Expected result:
----------------
The complete source code example in the english version is:
<?php
$arr = array(1, 2, 3, 4);
foreach ($arr as &$value) {
    $value = $value * 2;
}
// $arr is now array(2, 4, 6, 8)
unset($value); // break the reference with the last element
?>
