The IteratorAggregate interface

Увод

Interface to create an external Iterator.

Синтаксис за класове

IteratorAggregate
IteratorAggregate implements Traversable {
/* Methods */
abstract public Traversable getIterator ( void )
}

Example #1 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";
}
?>

Примерът по-горе ще изведе нещо подобно на:

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"
