인터페이스 개요

---

                  
interface IteratorAggregate extends Traversable {
  /* Methods */
  public getIterator(): Traversable
}
                  
                

Examples

예제 #1 기본 사용법

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

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

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

$obj = new myData;

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

위의 예는 다음과 유사한 결과를 출력합니다.

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"
