_values()

protected void _values ( string $key, mixed $val, array &$values )

Recursively pulls values from elements into an associative array.

Parameters

(string) $key: The current array key for the values array. If this has square brackets in it, that's a sign we need to keep creating sub-elements for the values array.
(mixed) $val: The element value to put into the values array, once we stop creating sub-elements based on the element name.
(array) &$values: The values array into which we will place the element value. Note that it becomes a reference to sub-elements as the recursive function creates new sub-elements based on the form element name.
