Получение данных из массива JSON в выражении PHP foreach

Question

Я пытаюсь получить данные из массива JSON - массив очень сложный по структуре.

Это мой массив:

IЯ пытаюсь получить ключевые результаты заголовка.Вот мой запрос:

$data = $someArray["data"];
foreach ($data as $result) {
    foreach ($result as $finalres) {
        echo $finalres["title"]."<br/>";
    }
  }
}

Вот результат, который я получаю.Список выводит на экран, но ошибка PHP показана выше и ниже.

Не знаю, почему предупреждение продолжает отображаться даже при отображении результатов?Как правильно отобразить список без ошибки PHP?

Answer 1

Чтобы вывести только результаты, вам просто нужно выбрать элементы 'webs' ...

foreach ($data['webs'] as $result) {

Ошибки, которые вы получаете, заключаются в том, что в первый раз он пытается использовать ...

[query] => Plagiarism is the "wrongful appropriation" and "stealing and publication"

и итерируйте по этому.

Answer 2

Попробуйте с этим кодом:

Рабочая демонстрация: https://eval.in/1017825

$data = $someArray["data"]['webs'];

foreach ($data as $finalres) 
{
    echo $finalres["title"].PHP_EOL;
}

Answer 3

попробуйте использовать ключ в foreach, как

foreach ($data as $key => $result) {}
