Map keys array to values array

Question

I have keys array and values array.

$keys = [
   0 => 'Test'
   1 => 'John'
   ...
   22 => 'Kate'
   23 => 'Bob'
]

I run an array_filter($values) to clear out unwanted empty values, then I end up with something like this

$values = [
   1  => '$3'
   22 => '$10'
   23 => '$50'
]

My goal is achieving

[
  'John' => '$3',
  'Kate' => '$10',
  'Bob'  => '$50'
]

Is there a way to map it this way without creating a for loop and a new array to assign each index individually?

I tried using array_intersect_key but couldn't get close at all.

Edit: My version looks like below but I'm sure there are better ways:

$selectedCols = array_intersect_key($keys, array_flip(array_keys($values)));
array_combine($selectedCols, $values);

You should first combine the two arrays using array_combine (https://www.php.net/manual/en/function.array-combine.php), then apply array_filter on the result. That should do it.

array_filter(array_combine($keys, $filters));
