Why do you even need the $cars array? Wouldn't this work?
foreach($models as $car => $model_array) {
foreach($model_array as $key => $model) {
print "The car is a $car $model";
}
}
If you know what manufacturer you want ('ford' or 'chevy') then you can
just get the models for that by doing this:
$car = 'ford';
foreach($models[$car] as $key => $model) {
print "The car is a $car $model";
}
