Note

This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.

Returns a Set containing the values after the n-th element of the current Set

public function skip(
  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 to be skipped; the $n+1 element will be the first one in the returned Set.

Returns​

  • Set<Tv> - A Set that is a proper subset of the current Set containing values after the specified n-th element.

Examples​

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

// Create a new Set after skipping the first two elements ('red' and 'green')
$skip2 = $s->skip(2);

\var_dump($skip2);
