HH\Set::take

Returns a Set containing the first n values of the current Set

public function take(
  int $n,
): Set<Tv>;

The returned Set will always be a proper subset of the current Set.

n is 1-based. So the first element is 1, the second 2, etc.

Parameters

• int $n - The last element that will be included in the Set.

Returns

• Set<Tv> - A Set that is a proper subset of the current Set up to n elements.

Examples

$s = Set {'red', 'green', 'blue', 'yellow'};

// Take the first two elements
$take2 = $s->take(2);

\var_dump($take2);
