我怎樣才能從這個多維數組中獲取數據

Question

我對從php php api客戶端返回的對象有些麻煩。我曾嘗試使用該標籤張貼，但沒有幫助。我已經將該對象轉換爲數組，但仍然無法弄清楚如何獲取我需要的所有數據。 基本上我使用谷歌API進行搜索，並將其返回的結果是如下（使用print_r的）一個對象：

Google_Service_Customsearch_Search Object ( 
[collection_key:protected] => promotions 
[internal_gapi_mappings:protected] => Array () 
[contextType:protected] => Google_Service_Customsearch_Context 
[contextDataType:protected] => 
[itemsType:protected] => Google_Service_Customsearch_Result 
[itemsDataType:protected] => 
array [kind] => customsearch#search 
[promotionsType:protected] => Google_Service_Customsearch_Promotion 
[promotionsDataType:protected] => array 
[queriesType:protected] => Google_Service_Customsearch_Query 
[queriesDataType:protected] => map 
[searchInformationType:protected] => Google_Service_Customsearch_SearchSearchInformation 
[searchInformationDataType:protected] => 
[spellingType:protected] => Google_Service_Customsearch_SearchSpelling 
[spellingDataType:protected] => 
[urlType:protected] => Google_Service_Customsearch_SearchUrl 
[urlDataType:protected] => 
[modelData:protected] => 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 - donkey 
      [totalResults] => 101000000 
      [searchTerms] => donkey 
      [count] => 5 
      [startIndex] => 6 
      [inputEncoding] => utf8 
      [outputEncoding] => utf8 
      [safe] => medium 
      [cx] => 000701869894579992216:cobbhbhbhbhre0 
      [searchType] => image 
      [imgSize] => large) 
     ) 
     [request] => Array ( 
      [0] => Array ( 
      [title] => Google Custom Search - donkey 
      [totalResults] => 101000000 
      [searchTerms] => donkey 
      [count] => 5 
      [startIndex] => 1 
      [inputEncoding] => utf8 
      [outputEncoding] => utf8 
      [safe] => medium 
      .... 
     ) 
     ) 
    ) 
    ) 
    [processed:protected] => Array () 
) 

我有麻煩獲取我想要的，因爲一些物品丟失值的值在這裏，第一個是[contextDataType：protected] => 這會導致各種各樣的問題，我不知道爲什麼對象是這樣返回的。所以我轉換爲數組： $ array =（array）$ results; 這給：

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 -

這看起來更有用，我可以展平陣列得到一些價值，但是由於按鍵被重用，然後我鬆散所有，但最後的結果。具體而言，我想獲得其中有5個，每個搜索結果中有一個的[鏈接]的所有值。

我該怎麼做？我相信這很容易，但我無法弄清楚。

感謝

OK我整理它，只是把它做成一個數組，然後使用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');
