Php-IteratorAggregate interface

The IteratorAggregate interface, a predefined API for PHP, is used to create an external iterator.

Interface abstract

IteratorAggregate extends Traversable {/* method */abstract public Traversable getIterator (void )}

Example #1 Basic usage

 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 output of the preceding routine is similar:

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"
