HH\Pair::skip

Returns an ImmVector containing the values after the n-th element of the current Pair

public function skip(
  int $n,
): ImmVector<mixed>;

n is 1-based. So the first element is 1, the second 2, etc. There is no element 3 in a Pair, but if you specify an element greater than or equal to 2, it will just return empty. If you specify 0, it will return all the elements in the Pair.

Parameters

• int $n - The last element to be skipped; the $n+1 element will be the first one in the returned ImmVector.

Returns

• ImmVector<mixed> - An ImmVector that contains values after the specified n-th element in the current Pair.

Examples

$p = Pair {'foo', -1.5};

// Skipping 0 returns an ImmVector of both values
\var_dump($p->skip(0));

// Skipping 1 returns an ImmVector of the second value
\var_dump($p->skip(1));

// Skipping more than 1 returns an empty ImmVector
\var_dump($p->skip(2));
