Решение
Просто используйте страницы как массив:
$response = json_decode(file_get_contents('https://en.wikipedia.org/w/api.php?action=query&prop=extracts&format=json&exintro=&titles=Stack%20Overflow'));
$pages = (array) $response ->query->pages;
foreach ($pages as $id => $page) {
echo $page->title;
}
Другие решения
использование formatversion=2 чтобы получить данные в более удобном для обработки формате.
$response = json_decode(file_get_contents('https://en.wikipedia.org/w/api.php?action=query&prop=extracts&format=json&formatversion=2&exintro=&titles=Stack%20Overflow'), true);
echo($response['query']['pages'][0]['title']);
