The ArrayIterator class

    (PHP 5, PHP 7, PHP 8)

    Introduction

    Allows the removal of elements, and the modification of keys or values while iterating over Arrays or Objects.

    When you want to iterate over the same array multiple times you need to instantiate ArrayObject and let it create ArrayIterator instances that refer to it either by using foreach or by calling its getIterator() method manually.

    Class synopsis

    class ArrayIterator implements SeekableIterator, ArrayAccess, Serializable, Countable {
    /* Constants */
    public const int STD_PROP_LIST;
    public const int ARRAY_AS_PROPS;
    /* Methods */
    public __construct(array|object $array = [], int $flags = 0)
    public append(mixed $value): void
    public asort(int $flags = SORT_REGULAR): true
    public count(): int
    public current(): mixed
    public getArrayCopy(): array
    public getFlags(): int
    public key(): string|int|null
    public ksort(int $flags = SORT_REGULAR): true
    public natcasesort(): true
    public natsort(): true
    public next(): void
    public offsetExists(mixed $key): bool
    public offsetGet(mixed $key): mixed
    public offsetSet(mixed $key, mixed $value): void
    public offsetUnset(mixed $key): void
    public rewind(): void
    public seek(int $offset): void
    public serialize(): string
    public setFlags(int $flags): void
    public uasort(callable $callback): true
    public uksort(callable $callback): true
    public unserialize(string $data): void
    public valid(): bool
    }

    Predefined Constants

    ArrayIterator Flags

    ArrayIterator::STD_PROP_LIST

    Properties of the object have their normal functionality when accessed as list (var_dump, foreach, etc.).

    ArrayIterator::ARRAY_AS_PROPS

    Entries can be accessed as properties (read and write).
