Also, AFAIK, PHP has always thrown a warning or notice if you use
foreach() on a non-associative array.  That doesn't mean it won't work,
but the strict standard is apparently:

foreach ($assoc as $key => $val)

not

foreach ($indexed as $item)

However, as we all know, the latter still works fine.

Despite the warning/notice you see, the code is probably still working
as expected (any other problems aside).  If you like to keep error
reporting on, you can just use an @ to suppress that error.
