ArrayIterator::offsetUnsetUnset value for an offset


public ArrayIterator::offsetUnset ( mixed $index ) : 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.



The offset to unset.
