MutableVector::slice

Returns a subset of the current MutableVector starting from a given key up to, but not including, the element at the provided length from the starting key

public function slice(
  int $start,
  int $len,
): MutableVector<Tv>;

$start is 0-based. $len is 1-based. So slice(0,2) would return the elements at key 0 and 1.

The returned MutableVector will always be a proper subset of this MutableVector.

Parameters

  • int $start - The starting key of this Vector to begin the returned MutableVector.
  • int $len - The length of the returned MutableVector.
