URL、タイトル、コンテンツが表示されるように、foreachループを使用してphpで解析しようとしています。ただし、コードを適切に解析できないようです。以下のコードでは、「responsedata」が認識されないというエラーが表示されます。

foreach($json as value)

echo $value [responsedata];

echo $value のままにしておくと、responsestatus の値である 200 という数字が表示されます。やってみると

foreach( $json =>url => title => content as $value)

「=」記号を認識しません。

何か案は？？あなたが投稿からそれを得ていないなら、私はJSONやphpにあまり精通していません:)

Answer 1

FTR、投稿したのは「json配列」ではなくネイティブ配列です。これを試してください：

$rawArray = get_results_somehow();

// Flatten the array to make it easier to work with
$results = $rawArray['responseData']['results'];

foreach ($results as $result) {

    // Should now see the expected values
    var_dump($result);
}

Answer 2

そのデータはすでに配列形式になっています。このように $array['responseData']['results'] を繰り返す必要があります。

$arr = $array['responseData']['results'];

foreach($arr as $k){
   echo $k['url'];
   echo $k['title'];
   echo $k['content'];
}
