As far as I know, no.

while (list(, $grade) = each($grades) && list(, $course) = each($courses))
Would do what you're trying to do.

Also if the arrays directly correspond, which I assume they do, since it doesn't make sense to process them concurrently if not, you can do something like
foreach ($grades as $key=>$grade)
// $class' corresponding element to the current $grade is $class[$key]
$keys = count($grades);
for ($ii = 0; $ii < $keys; ++$ii)
// corresponding elements are $grades[$ii] and $class[$ii]
