HH\ImmSet::toKeysArray

Returns an array containing the values from the current ImmSet

public function toKeysArray(): varray<Tv>;

Sets don't have keys. So this method just returns the values.

This method is interchangeable with toValuesArray().

Returns

• varray<Tv> - an integer-indexed array containing the values from the current ImmSet.
