The MultipleIterator class

(PHP 5 >= 5.3.0, PHP 7, PHP 8)

Introduction

An Iterator that sequentially iterates over all attached iterators

class MultipleIterator implements Iterator {

/* Constants */

const int MIT_NEED_ANY = 0;

const int MIT_NEED_ALL = 1;

const int MIT_KEYS_NUMERIC = 0;

const int MIT_KEYS_ASSOC = 2;

/* Methods */

public __construct(int $flags = MultipleIterator::MIT_NEED_ALL | MultipleIterator::MIT_KEYS_NUMERIC)

public attachIterator(Iterator $iterator, string|int|null $info = null): void

public containsIterator(Iterator $iterator): bool

public current(): array

public detachIterator(Iterator $iterator): void

public getFlags(): int

public key(): array

public next(): void

public rewind(): void

public setFlags(int $flags): void

public valid(): bool

}

MultipleIterator::MIT_NEED_ANY: Do not require all sub iterators to be valid in iteration.
MultipleIterator::MIT_NEED_ALL: Require all sub iterators to be valid in iteration.
MultipleIterator::MIT_KEYS_NUMERIC: Keys are created from the sub iterators position.
MultipleIterator::MIT_KEYS_ASSOC: Keys are created from sub iterators associated information.
