I have a somewhat novice question about creating a tree structure out of a flat set of data. I basically want to take a number of arrays and store them in one structure.

To start with, I need to know how to store an array of values in another array, in code like this: 

sub recursive_store {
$query[$level] = "sql code here";
$query[$level]->execute;
while((_STORAGE[$level])=$query[$level]->fetchrow_array) {
print _STORAGE[$level][0]; 
} 
}

&recursive_store($level);

I'm not sure what syntax to use for storing and then retrieving the arrays returned by the while condition. The purpose is then to be able to go: 
print _STORAGE[$anylevel][$anyindex];

Basically I need to access an array of arrays but the samples I've seen weren't really clear on how to achieve that.
