How to use filter_input for key and value?

Question

PHP

Good afternoon.
When we expect an array of numbers, we can use the code

filter_input(INPUT_POST, 'arr', FILTER_VALIDATE_INT, FILTER_REQUIRE_ARRAY);

What about when I expect an associative array where the keys should be strings and the values ​​should be numbers?
Only build a construction from filter_input() + filter_var() for keys?
Thank you.
