}Example #1 基本用法
<?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";
}
?>以上例程的输出类似于：
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"
