Answer 1

그냥 배열로 페이지를 사용

$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; 
} 

Answer 2

사용 formatversion=2가 쉽게 처리 할 수있는 형식으로 데이터를 얻을 수 있습니다.

$response = json_decode(file_get_contents('https://en.wikipedia.org/w/api.php?action=query&prop=extracts&format=json&formatversion=2&exintro=&titles=Stack%20Overflow'), true); 
echo($response['query']['pages'][0]['title']);
