Unset value for an offset
Description
ArrayIterator::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
keyThe offset to unset.
Return Values
Void
