親子関係の配列

Question

私は親と子で構成されるカテゴリ配列を持っています。誰かがforeachループでparent_idとcategory_idを使用して、配列の配列を整理する手助けをすることができます。一番上のParentのparent_idは「0」です。 category_idとparent_id以外のフィールドは無視してください。ここに私の配列です。

Answer 1

機能

function get_childs($arr, $parent_id = 0) { 
    $res = array(); 
    foreach ($arr as $row) { 
     if ($parent_id == $row['parent_id']) { 
       $childs = get_childs($arr, $row['category_id']); 
       $row['childs'] = $childs; 
       $res[] = $row; 
     } 
    } 
    return $res; 
} 

を考えてみましょうその後、両親を取得するには、この機能を使用すると、それはあなたがあなたの期待出力を共有することができます

$res = get_childs($arr);
