我在 SQL 查询中有一个组列表,并希望将它们输出到一个数组中,以便以后可以引用它。
目前我有以下代码循环遍历组并将它们放入$test_array
:
$test_array = array();
$query = $this->site_model->list_groups();
foreach($query as $r1) :
$test_array[] = $r1->group_name;
endforeach;
这显示了以下数组:
Array
(
[0] => Group 1
[1] => Group 2
[2] => Group 3
[3] => Group 4
[4] => Group 5
[5] => Group 6
[6] => Group 7
[7] => Group 8
)
我想要将相同的查询传递给如下所示的数组,以便稍后将其他段添加到数组中:
Array
(
[Round 1] => Array
(
[0] => Group 1
[1] => Group 2
[2] => Group 3
[3] => Group 4
[4] => Group 5
[5] => Group 6
[6] => Group 7
[7] => Group 8
)
)
这可能吗?
