這裏是我做了迄今爲止代碼：

$i=1;  
    foreach($data->webPages->value as $val){ 
     if($i==1){ 
      $part = $val['deepLinks']->snippet; 
     } 
    $i++;  
    }

結果：Fatal error: Cannot use object of type stdClass as array.

如何獲取價值？

如果您將其編輯爲包含您試圖解析的JSON樣本，此問題會更好。否則，我們只能猜測。 – mkaatman

我試圖編輯代碼，但仍然錯誤json代碼 –

添加您正在處理您的問題的JSON示例。我們不是魔術師！ – mkaatman

我認爲這可能與$數據有關。它不是一個數組。

您是否使用json_decode（）將您的JSON對象轉換爲PHP變量？如果是，那麼你需要將其更改爲：

json_decode($myJSON, true);

如果設置爲true，PHP將返回一個關聯數組但如果不是PHP將返回一個對象（stdClass的）。

您可以瞭解更多有關這是爲什麼here

yes，$ data = json_decode（$數據）;那麼我想在深度鏈接中獲得價值 –

@sugiputra將其更改爲我在答案中所說的內容。這應該使它工作。 – FrenchMajesty

我有更改$ data = json_decode（$ data）;到json_decode（$ data，true）;出現錯誤：嘗試獲取非對象的屬性在 –

如果你想深層鏈接的平面陣列，試試這個：

$ret = []; 
foreach($data->webPages->value as $val){ 
    if(property_exists($val,"deepLinks")){ 
     $ret = array_merge($ret, $val->deepLinks); 
    } 
} 
var_dump($ret);

我測試了它和它的作品。

在另一方面，如果你想獲得它分爲：

$ret = []; 
foreach($data->webPages->value as $val){ 
    if(property_exists($val,"deepLinks")){ 
     $ret[] = $val->deepLinks; 
    } 
} 
var_dump($ret);

測試JSON我使用：

$data = '{
