The RecursiveArrayIterator class

(PHP 5 >= 5.1.0, PHP 7, PHP 8)

This iterator allows for unsetting and modifying values and keys while iterating over arrays and objects, in the same way as the ArrayIterator. Additionally, it is possible to iterate over the current iterator entry.

class RecursiveArrayIterator extends ArrayIterator implements RecursiveIterator {

/* 继承的常量 */

public const int ArrayIterator::STD_PROP_LIST;

public const int ArrayIterator::ARRAY_AS_PROPS;

/* 常量 */

public const int CHILD_ARRAYS_ONLY;

/* 方法 */

public function getChildren(): ?RecursiveArrayIterator

public function hasChildren(): bool

/* 继承的方法 */

public function ArrayIterator::count(): int

public function ArrayIterator::current(): mixed

public function ArrayIterator::getArrayCopy(): array

public function ArrayIterator::offsetExists(mixed $key): bool

public function ArrayIterator::offsetGet(mixed $key): mixed

public function ArrayIterator::offsetSet(mixed $key, mixed $value): void

public function ArrayIterator::offsetUnset(mixed $key): void

public function ArrayIterator::rewind(): void

public function ArrayIterator::seek(int $offset): void

public function ArrayIterator::serialize(): string

public function ArrayIterator::uasort(callable $callback): true

public function ArrayIterator::uksort(callable $callback): true

public function ArrayIterator::unserialize(string $data): void

public function ArrayIterator::valid(): bool

}

RecursiveArrayIterator::CHILD_ARRAYS_ONLY: Treat only arrays (not objects) as having children for recursive iteration.
