<?php
echo "<small><pre>";

/* for some reason the following code magically kills
   an array value, or better, overwrites it with another one.
   might be related to bug #6417 */

$arr = array('a','b');
$ref =& $arr[0];

print_r($arr);
/* gives: Array ( [0] => a [1] => b ) */

foreach($arr as $ref);
print_r($arr);

/* gives: Array ( [0] => b [1] => b ) */
?>

well, maybe this behaviour is not so weird as I tought...
the problem I had, was that the line taking the reference
and the foreach-statement were far apart, and I'd really
like to have localized variables in the foreach, like
foreach($arr as (my $val))...

no bug, closing

ps. this is PHP there won't be local variables like the ones you proposed in the near future I guess
