IteratorAggregate (interface)
IteratorAggregate 接口
介绍
(PHP 5 >= 5.0.0, PHP 7)
创建外部迭代器的接口。
界面简介
IteratorAggregate extends Traversable {
/* Methods */
abstract public Traversable getIterator ( void )
}
示例＃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";
}
?>
上面的例子会输出类似于：
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"
