(PHP 5 >= 5.0.0, PHP 7)
Examples:
Basic usage
<?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"; } ?>
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"
