Merging two product star ratings with foreach in Woocommerce - php

Question

There may be a better way to state the question, but I'm workin' with what I know.
On Woocommerce I'm trying to get the _wc_rating_count for each star (1-5), but also for two products; then I want to combine theme; e.g., I am merging the reviews of two products on one page, in one graph.
I am doing that this way:
$product_id = array( 2146, 2166 );
$ratings = array(5, 4, 3, 2, 1);
foreach ($product_id as $pid) :
$product = wc_get_product($pid);
foreach ($ratings as $rating) :
$rating_count = $product->get_rating_count($rating);
$percentage = ($rating_count / $count) * 100 . "%";
//echo $rating_count . '<br/>';
endforeach;
endforeach;
The problem is, I'm getting an array of 10 items (2 products x 5 star ratings( 5,4,3,2,1), and I need those values merged.
11
1
0
0
2
8
0
0
0
1
Where I need it to be
19
1
0
0
3
Do you know how I may get two arrays out of the embedded foreachs and merge them based on the $ratings array?
Thanks for your help :)

So here is what do you like to achieve:
$product_ids = array( 2146, 2166 );
$ratings = array(5, 4, 3, 2, 1);
$rate_countings = array();
foreach ($product_ids as $pid){
$product = wc_get_product($pid);
foreach ($ratings as $rating){
$rating_count = $product->get_rating_count($rating);
//$percentage = ($rating_count / $count) * 100 . "%";
if( !isset($rate_countings[$rating]) ){
$rate_countings[$rating] = 0;
}
$rate_countings[$rating] += $rating_count;
}
}
var_dump($rate_countings);
