In the following example:

foreach ($results as $key => $item)  {

   //bla bla bla -- unset some of the $items


I want to modify $results within the foreach. In other words,
during a given pass of this iteration, I want to delete some
of the items based on particular conditions. Then on the next
pass thru the foreach, I want $results to be the newer, modified

This does not seem to work. It appears that the foreach statement
is implemented such that $results is read into memory at the start
so that any modifications I make to it during a given pass, are ignored
on the next pass. Is this true?

If so, is there a way that I can tell the foreach statement to re-read the
array $results?  Or am I just going against the grain here?
