I am not 100% sure I have understood your problem but the following works
for the way I envisaged your arrays:-
$brands = array('porsche', 'ford');
$porsche = array('911');
$ford = array('escort');
foreach ($brands as $r)
{
foreach (${$r} as $model)
{
echo $model;
}
}
The error you have suggests that you are not passing an array to the foreach
loop instead you are passing a value.
