を持っており、ここで私はこれまでやったコードはJSONオブジェクトですか？

Answer 1

私は$ dataと関係があると思います。これは配列ではありません。

json_decode（）を使用してJSONオブジェクトをPHP変数に変換しましたか？連想配列が、を返します真のPHPに設定した場合、それはオブジェクト（はstdClass）を返しますPHPでない場合

json_decode($myJSON, true); 

：はい場合は、それを変更する必要があります。あなたはディープリンクの平らな配列をしたい場合あなたはそれがhere

Answer 2

である理由の詳細を読むことができ

、これを試してみてください。

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

私はそれをテストし、それが動作します。一方

、あなたはそれがグループ化された取得したい場合：

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