どのように配列を結合し、自分の配列をIDで作るのですか？

Question

私はデータベースにクエリを作成し、これを印刷します。ご覧のとおり、page_id => 2は1つの配列にすることができます。

Array 
(
    [page_id] => 3 
    [name] => Add Me 
    [article_category] => Celebrities 
    [count_article_category] => 1 
    [average_ctr] => 5.555560111999512 
) 
Array 
(
    [page_id] => 2 
    [name] => I Too Had a Love Story 
    [article_category] => Celebrities 
    [count_article_category] => 7 
    [average_ctr] => 2.525434238570077 
) 
Array 
(
    [page_id] => 2 
    [name] => I Too Had a Love Story 
    [article_category] => Desi 
    [count_article_category] => 1 
    [average_ctr] => 2.892319917678833 
) 
Array 
(
    [page_id] => 2 
    [name] => I Too Had a Love Story 
    [article_category] => Lifestyle 
    [count_article_category] => 1 
    [average_ctr] => 2.3632400035858154 
) 
Array 
(
    [page_id] => 2 
    [name] => I Too Had a Love Story 
    [article_category] => Sports 
    [count_article_category] => 1 
    [average_ctr] => 2.150439977645874 
) 
Array 
(
    [page_id] => 1 
    [name] => Indian Celebrities 
    [article_category] => Celebrities 
    [count_article_category] => 2 
    [average_ctr] => 2.7356200218200684 
) 
Array 
(
    [page_id] => 1 
    [name] => Indian Celebrities 
    [article_category] => Hilarious 
    [count_article_category] => 1 
    [average_ctr] => 0.7684919834136963 
) 

このような配列が必要です。

[2] 
    (
     [Celebrities] => 7 
     [Lifestyle] => 1 
     [Desi] => 1 
    ) 

私はforeachループで実行される次のコードを試してみました。私の論理やコーディングが間違っていることを理解していますが、私は間違いを理解することができません。
助けてください。

if (isset($data['page_id'])) 
{ 
    if (array_key_exists($data['page_id'], $pages_data)) 
    { 
    echo "<pre>"; 
    var_dump($pages_data); 
    $pages_data[$data['page_id']] += array(
     $data['article_category'] => $data['count_article_category'], 
    ); 
    } else { 
    // $pages_data[$data['article_category']] = $data['average_ctr']; 
    // $pages_dat a[$data['page_id']] = $data['page_id']; 
    $pages_data[$data['page_id']] = array(
     $data['article_category'] => $data['count_article_category'], 
    ); 
    } 
    echo "<pre>"; 
    print_r($pages_data); 
}

さて、ここで私達は行く：

$pages_data = array(); 
foreach ($datas as $data) { 
    if (isset($data['page_id'])) { 
     // create new element for $pages_data[$data['page_id']] if it does not exists 
     if (!isset($pages_data[$data['page_id']])) { 
      $pages_data[$data['page_id']] = array(); 
     } 

     // if it exists - just add certain values: 
     $pages_data[$data['page_id']][$data['article_category']] = $data['count_article_category']; 
    } 
}
