我遇到了一个从谷歌php api客户端返回的对象有问题。我试过使用该标签发布但没有帮助。我已经将对象转换为数组，但仍然无法弄清楚如何获取我需要的所有数据。 基本上我正在使用谷歌api进行搜索，它返回一个对象，结果如下（使用print_r）：
Google_Service_Customsearch_Search Object (

我在检索我想要的值时遇到问题，因为有些项目缺少值，第一个是[contextDataType：protected] =＆gt; 这会导致各种各样的问题，我不确定为什么会像这样返回对象。
所以我转换成了一个数组： $ array =（array）$ results; 这给出了：
Array ( [*collection_key] => promotions [*internal_gapi_mappings] => Array ( ) [*contextType] => Google_Service_Customsearch_Context [*contextDataType] => [*itemsType] => Google_Service_Customsearch_Result [*itemsDataType] => array [kind] => customsearch#search [*promotionsType] => Google_Service_Customsearch_Promotion [*promotionsDataType] => array [*queriesType] => Google_Service_Customsearch_Query [*queriesDataType] => map [*searchInformationType] => Google_Service_Customsearch_SearchSearchInformation [*searchInformationDataType] => [*spellingType] => Google_Service_Customsearch_SearchSpelling [*spellingDataType] => [*urlType] => Google_Service_Customsearch_SearchUrl [*urlDataType] => [*modelData] => Array ( [url] => Array ( [type] => application/json [template] => https://www.googleapis.com/customsearch/v1?q={searchTerms}&num={count?}&start={startIndex?}&lr={language?}&safe={safe?}&cx={cx?}&cref={cref?}&sort={sort?}&filter={filter?}&gl={gl?}&cr={cr?}&googlehost={googleHost?}&c2coff={disableCnTwTranslation?}&hq={hq?}&hl={hl?}&siteSearch={siteSearch?}&siteSearchFilter={siteSearchFilter?}&exactTerms={exactTerms?}&excludeTerms={excludeTerms?}&linkSite={linkSite?}&orTerms={orTerms?}&relatedSite={relatedSite?}&dateRestrict={dateRestrict?}&lowRange={lowRange?}&highRange={highRange?}&searchType={searchType}&fileType={fileType?}&rights={rights?}&imgSize={imgSize?}&imgType={imgType?}&imgColorType={imgColorType?}&imgDominantColor={imgDominantColor?}&alt=json ) [queries] => Array ( [nextPage] => Array ( [0] => Array ( [title] => Google Custom Search -

这看起来更有用，我可以将数组展平以获得一些值，但由于键被重用，我会松开除最后一个结果之外的所有值。具体来说，我希望获得[link]的所有值，其中每个搜索结果中有5个，一个。
我该怎么办？我确信这很容易，但我无法理解。

好的我对它进行了排序，只是把它变成了一个数组，然后使用了array_walk_recursive：
//Making the returned object into an array
$array = (array) $results;
function array_print($item, $key)
{
if($key=='link'){
echo $item ."<br>";
}
}
array_walk_recursive($array, 'array_print');
