No, that didn't do it but thanks anyway. I figured it out eventually -
this seems to do the trick:
foreach ($brands as $curbrand) {
$cars = ${$curbrand[brandcode]};
echo $curbrand[brandname];
foreach ($cars as $curcar) {
echo $curcar;
}
}
It basically echoes the brandname followed by all the cars in the
array of the same name. $cars = ${$curbrand[brandcode]} was the main
bit I was looking for - assigning a variable as the array name.
