get values ​​from an array

Hello, I hope not to bother I have a basic question but that so far I have not understood.

I have several values inside a meta key and when retrieving them I get an array clearly. The problem is that I don’t know how to get the values only. It would be like this:

get_user_meta ($ vendor_id, ‘subscribers2’, false);

within the subscribers2 meta there are, for example, 3 email addresses 1@gmail.com, 2@gmail.com and 3@gmail.com.

well how do i get that?

at the moment I can’t, I just get a simple Array or this:

$ emails_todos_subscrip = get_user_meta ($ vendor_id, ‘subscribers2’, false);
echo print_r ($ emails_all_subscription);

ArrayArray ([0] => Array ([0] => Array ([0] => 111@gmail.com [1] => 111@gmail.com [2] => 111@gmail.com [3] = > 111@gmail.com [4] => 111@gmail.com [5] => 111@gmail.com [6] => 111@gmail.com [7] => 111@gmail.com [8] = > tiendanannn@gmail.com) [1] => Array ([0] ……

and so much more of the same.

I appreciate your help.
