If I call another function script_loader_tag, it loops through the results from the function as many times as they are script values associated with $tag.

For example, here’s a simple function

function test() {
    $test_value = array ('a', 'b', 'c');
    return $test_value;
}

If this function is called in script_loader_tag e.g var_dump($skip);, it outputs the below which mirrors the number of scripts.

array(3) {
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
}

array(3) {
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
}
