Description:
------------
I think this was introduced with #15488.

It states 
"/* foreach example 2: value (with key printed for illustration) */" 

but the example doesn't really print that key.

Thanks

Reproduce code:
---------------
http://www.php.net/manual/en/control-structures.foreach.php

Expected result:
----------------
/* foreach example 2: value (with key printed for illustration) */

$a = array(1, 2, 3, 17);

foreach ($a as $i => $v) {
    echo "\$a[$i] => $v.\n";
}

Actual result:
--------------
/* foreach example 2: value (with key printed for illustration) */

$a = array(1, 2, 3, 17);

$i = 0; /* for illustrative purposes only */

foreach ($a as $v) {
    echo "\$a[$i] => $v.\n";
    $i++;
}
