When I run
count(array_filter($mm)) I get
3 as result since it is not recursive.
count(array_filter($mm), COUNT_RECURSIVE) also will not do because I actually need to run the

If you are using PHP in a pre-5.3 version, I would use a
Regarding the comment below:
When this is really only, what you want, the solution is very simple too. But now I don't know, how to interpret
Anyway, its short now :)
The resulting array looks like
