(PHP 5, PHP 7, PHP 8)
Interface to create an external Iterator.
Example #1 Basic usage
<?phpclass 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";}?>
The above example will output something similar to:
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"
