我有一个函数foo，它返回一个具有以下结构的数组，我正在努力解决是否有更好的方法来构建我的 PHP，因为我不确定 foreach 中的索引，因为我想要每个ListingId

目标：

我想编写一个从外部 XML 文档foreach中获取 XML 的循环<Name>（尚未编写此部分，因为我需要将ListingIDfrom传递foo到 url 以获取<Name>）

PHP：

    $test0 = $this->foo();
    $test = $test0[0]['ListingId'];

结构：

Array ( [0] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 532712629 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3400- ) ) [1] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 532712202 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3400- ) ) [2] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 532711566 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3400- ) ) [3] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 532710864 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3400- ) ) [4] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 532710271 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3400- ) ) [5] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 532691526 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3400- ) ) [6] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 527496168 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3399- ) ) )

试试这个方法：

foreach($this->foo() as $foo) {
   //here you can use your ListingId
   var_dump($foo['ListingId']);
}
