The IteratorAggregate interface

    (PHP 5, PHP 7, PHP 8)

    Introdução

    Interface para criar um iterador externo.

    Resumo da Interface

    interfaceIteratorAggregateextendsTraversable {
    publicgetIterator(): Traversable
    }

    Exemplos

    Exemplo #1 Basic usage

    <?php

    class myData implements IteratorAggregate
    {
    public     $property1 = "Public property one";
    public     $property2 = "Public property two";
    public     $property3 = "Public property three";
    public     $property4 = "";

    public function     __construct()
    {
    $this->property4 = "last property";
    }

    public function     getIterator(): Traversable
    {
    return new     ArrayIterator($this);
    }
    }

    $obj = new myData();

    foreach (    $obj as $key => $value) {
    var_dump($key, $value);
    echo     "\n";
    }

    ?>

    O exemplo acima produzirá algo semelhante a:

     string(9) "property1" string(19) "Public property one" string(9) "property2" string(19) "Public property two" string(9) "property3" string(21) "Public property three" string(9) "property4" string(13) "last property"
