I've run into this type of error a few different times.  I found a good
reference for changing the command from foreach to a while command.  The
reference is here...

http://phpmirror.unrealghetto.com/manual/en/control-structures.foreach.php

more specifically

$arr = array("one", "two", "three");
reset($arr);
while (list($key, $value) = each($arr)) {
   echo "Key: $key; Value: $value<br />\n";
}

foreach ($arr as $key => $value) {
   echo "Key: $key; Value: $value<br />\n";
}

or

$arr = array("one", "two", "three");
reset($arr);
while (list(, $value) = each($arr)) {
   echo "Value: $value<br />\n";
}

foreach ($arr as $value) {
   echo "Value: $value<br />\n";
}

This kind of gives an idea of how to translate the foreach into a while
statement.

I don't know if this is a problem specific to the alpha releases or
perhaps php-4.3.8 i've been using. But the changes have solved the
problems for me.  Maybe Chuck or Jan can chime in on what I've said.

Hope this information is of use.
