ArrayIterator::offsetUnset

(PHP 5, PHP 7)

ArrayIterator::offsetUnsetUnset value for an offset


Description

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.


Parameters

index
The offset to unset.


Return Values

No value is returned.
