首先抱歉，如果问题不好，我的英语不太好。

我有以下查询

SELECT 
    * 
FROM 
    `stream_post` 
        LEFT JOIN `stream_comment` 
            ON (`stream_post`.`stream_id` = `stream_comment`.`comment_stream_id`) 
        JOIN `users_metadata` 
            ON (`stream_post`.`user_id` = `users_metadata`.`user_id`) 
ORDER BY 
    `stream_id` DESC 
LIMIT 10

问题实际上是我想在同一页面上使用这些评论

所以它看起来像这样

parrent post 1
   children comment 1
   children comment 1

parrent post 2
   children2 comment 1
   children2 comment 1

我也将帖子 ID（流 ID 是什么）保存在评论表中并加入它们。

但是当我得到结果时，看起来像这样

所以问题是当我遇到这些时，我得到的评论是分开的，还是合并的？

所以我想看起来像这样

有没有办法做到这一点？请有人给我一个提示或一个例子吗？

真的会很开心

很抱歉，但事情就是这样。除非您将所有数据放在一个数组中，否则您可以使用 foreach 或 for 语句按顺序遍历 comment_text。

数组中不能有两个同名的键。您需要在进行时重命名密钥（可能在末尾附加一个数字）

[comment_text_1] => comment one
[comment_text_2] => comment two

或者你可以把每个元素变成一个像这样的子元素数组——这在代码中更有用

[comment_text] => array('comment one', 'comment two')
