How to make a 'simple query' of a large array? [closed]

[DaviD18]

I've got this line of code:\[code\]// echo the name of one forum (without additional DB query)echo ($mybb->cache->cache['forums'][19][name]);\[/code\]This gives the name of one forum. I need to list all forums by "querying" the array. Obviously, a simple db query could do this, but the info is already available.How to iterate all the 'forums' and echo their name?
