That code is actually very close to what you need. What you need to do
is to put the store's name, which is the index of the first level. As
it is, the first foreach is completely ignoring the indexes of the first
level.
$store is ends up being the array for the second foreach, but to the
first foreach it's nothing but the "value" of the first level array.
Basically, you need to setup the first foreach to look much like the
second foreach.
foreach will only handle one dimension at a time. Which is why I find it
easier to term each dimension as really a "level" in multi-dimensional
arrays.
Sorry for being vague; I could outright show what the first two lines
need to be to get what you want, but this looks like a homework
question. And even if it's not, you're so close with what you have that
I'd think it be better to try to nudge you in the right direction.
