Question

如何解析XML并获取节点。

Answer 1

你可以使用json_decode字符串解码，一个递归函数删除所有不活动的元素，最后json_encode恢复数组的JSON字符串

$json = json_decode($data, true); 
$json['categoryTree'] = filter_inactive($json['categoryTree']); 
echo json_encode($json); 

function filter_inactive($data) { 
    $t = array(); 
    foreach ($data as $child) { 
     if ($child['is_active'] == '1') { 
      if (isset($child['children'])) { 
       $child['children'] = filter_inactive($child['children']); 
      } 
      $t[] = $child; 
     } 
    } 

    return $t; 
}
