    ArrayIterator::offsetUnset — Unset value for an offset

    Description

    publicArrayIterator::offsetUnset(mixed$key): void

    Unsets a value for an offset.

    If iteration is in progress, and ArrayIterator::offsetUnset() is used to unset the current index of iteration, the iteration position will be advanced to the next index. Since the iteration position is also advanced at the end of a foreach loop body, use of ArrayIterator::offsetUnset() inside a foreach loop may result in indices being skipped.

    Parameters

    key

    The offset to unset.

    Return Values

    No value is returned.
