wp_insert_post two values into the post_title

I’m currently working on inserting some data into my posts, I’m trying to insert two sets of data into the post title and I’m kinda stuck.

$my_post = array(
    'post_title' => $data['title'],

This works fine, but I need to add another one to the title, how can I do that? for example

'post_title' => $data['title'] && $data['count'],

Any help would be appreciated, thank you.
