Just use pages as array:

$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;
}

Use formatversion=2 to get the data in an easier to handle format.

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