ArrayIterator::offsetUnset
(PHP 5, PHP 7, PHP 8)
ArrayIterator::offsetUnset — Unset value for an offset
Description
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.
