我有一个查询
SELECT bs.i_description,col.Column_name,bs.Tm_id,ad.UserName as name,
a.fk_sprint_id as spid,b.fk_back_id,b.u_pos_is,b.s_id,b.color,b._left,b._top,
b.wiptime as wiptime,b.dodtime as dodtime,b.Dep_status
FROM backToSprint a
JOIN backToSprint b ON a.`s_id` = b.`fk_f_id`
join backlog bs on bs.b_id=b.fk_back_id
left join admin ad on bs.Tm_id=ad.adminID
left join admin_column col on col.column_id=b.u_pos_is
where a.fk_sprint_id=3 and a.teamid=1
ORDER BY a.`fk_f_id`
我在哪里得到
Array
(
[0] => Array
(
[i_description] => Story 1
[Column_name] => Backlogs
[Tm_id] => 0
[name] =>
[spid] => 3
[fk_back_id] => 408
[u_pos_is] => 1
[s_id] => 5
[color] => 2
[_left] => 18
[_top] => -9
[wiptime] =>
[dodtime] =>
[Dep_status] => 0
)
[1] => Array
(
[i_description] => Story 2
[Column_name] => Backlogs
[Tm_id] => 0
[name] =>
[spid] => 3
[fk_back_id] => 409
[u_pos_is] => 1
[s_id] => 6
[color] => 3
[_left] => 18
[_top] => -9
[wiptime] =>
[dodtime] =>
[Dep_status] => 0
)
)
此处列名相同，因此我希望输出类似
Array
(
['c'] => Array
(
[Column_name] => Backlogs
)
[0] => Array
(
[i_description] => Story 1
[Column_name] => Backlogs
[Tm_id] => 0
[name] =>
[spid] => 3
[fk_back_id] => 408
[u_pos_is] => 1
[s_id] => 5
[color] => 2
[_left] => 18
[_top] => -9
[wiptime] =>
[dodtime] =>
[Dep_status] => 0
)
[1] => Array
(
[i_description] => Story 2
[Column_name] => Backlogs
[Tm_id] => 0
[name] =>
[spid] => 3
[fk_back_id] => 409
[u_pos_is] => 1
[s_id] => 6
[color] => 3
[_left] => 18
[_top] => -9
[wiptime] =>
[dodtime] =>
[Dep_status] => 0
)
)
然后我尝试了
$this->view->getstories['c'] = ['Column_name' => array_unique(array_column( $this->view->getstories, 'Column_name'))];
没有得到实际的输出。我得到了类似的输出
Array
(
[0] => Array
(
[i_description] => Story 1
[Column_name] => Backlogs
[Tm_id] => 0
[name] =>
[spid] => 3
[fk_back_id] => 408
[u_pos_is] => 1
[s_id] => 5
[color] => 2
[_left] => 18
[_top] => -9
[wiptime] =>
[dodtime] =>
[Dep_status] => 0
)
[1] => Array
(
[i_description] => Story 2
[Column_name] => WIP
[Tm_id] => 0
[name] =>
[spid] => 3
[fk_back_id] => 409
[u_pos_is] => 2
[s_id] => 6
[color] => 3
[_left] => 18
[_top] => -9
[wiptime] =>
[dodtime] =>
[Dep_status] => 0
)
[c] => Array
(
[Column_name] => Array
(
[0] => Backlogs
[1] => WIP
)
)
)
（这里我还有另一个列名WIP） 但是我想要像这样的嵌套数组
Array
(
[c1] => Array
(
[Column_name] => Array
(
[0] => Backlogs
)
[0] => Array
(
[i_description] => Story 1
[Column_name] => Backlogs
[Tm_id] => 0
[name] =>
[spid] => 3
[fk_back_id] => 408
[u_pos_is] => 1
[s_id] => 5
[color] => 2
[_left] => 18
[_top] => -9
[wiptime] =>
[dodtime] =>
[Dep_status] => 0
)
[c2] => Array
(
[Column_name] => Array
(
[0] => WIP
)
[0] => Array
(
[i_description] => Story 2
[Column_name] => WIP
[Tm_id] => 0
[name] =>
[spid] => 3
[fk_back_id] => 409
[u_pos_is] => 2
[s_id] => 6
[color] => 3
[_left] => 18
[_top] => -9
[wiptime] =>
[dodtime] =>
[Dep_status] => 0
)
)
)
请帮助我解决此问题 任何帮助将不胜感激。

您想要的是嵌套数组。在使用$row['Column_name']作为主数组的键从查询中获取行的同时，将每一行推入该嵌套数组中。
$results = [];
while ($row = $stmt->fetch()) {
$results[$row['Column_name']][] = $row;
}
这将产生如下结果：
Array
(
[Backlogs] => Array
(
[0] => Array
(
[i_description] => Story 1
[Column_name] => Backlogs
[Tm_id] => 0
[name] =>
[spid] => 3
[fk_back_id] => 408
[u_pos_is] => 1
[s_id] => 5
[color] => 2
[_left] => 18
[_top] => -9
[wiptime] =>
[dodtime] =>
[Dep_status] => 0
)
)
[WIP] => Array
(
[0] => Array
(
[i_description] => Story 2
[Column_name] => WIP
[Tm_id] => 0
[name] =>
[spid] => 3
[fk_back_id] => 409
[u_pos_is] => 2
[s_id] => 6
[color] => 3
[_left] => 18
[_top] => -9
[wiptime] =>
[dodtime] =>
[Dep_status] => 0
)
)
)
)
不需要c1和c2键，只需使用Column_name值作为主数组的键即可。
