Question

我需要更改在CodeIgniter中返回的数组的格式，将数据库的字段保留为索引，我在PHP和CodeIgniter中进行了相同的查询，并且两者是不同的，有什么建议吗？我在CodeIgniter中使用result_array（），也在result（）中使用

我需要这个：

Array
(
    [1_1] => Array
        (
            [0] => 1_1
            [1] => 16
            [2] => ch
            [3] => Chemistry
        )

    [1_2] => Array
        (
            [0] => 1_2
            [1] => 17
            [2] => ch
            [3] => Chemistry
        )

    [2_3] => Array
        (
            [0] => 2_3
            [1] => 18
            [2] => ch
            [3] => Chemistry
        )

    [2_5] => Array
        (
            [0] => 2_5
            [1] => 19
            [2] => ch
            [3] => Chemistry
        )

    [9_1] => Array
        (
            [0] => 9_1
            [1] => 20
            [2] => ch
            [3] => Chemistry
        )

)

查询结果：

Array
(
    [0] => Array
        (
            [pos] => 1_1
            [tbl_id] => 16
            [sub_id] => ch
            [sub_name] => Chemistry
        )

    [1] => Array
        (
            [pos] => 1_2
            [tbl_id] => 17
            [sub_id] => ch
            [sub_name] => Chemistry
        )

    [2] => Array
        (
            [pos] => 2_3
            [tbl_id] => 18
            [sub_id] => ch
            [sub_name] => Chemistry
        )

    [3] => Array
        (
            [pos] => 2_5
            [tbl_id] => 19
            [sub_id] => ch
            [sub_name] => Chemistry
        )

    [4] => Array
        (
            [pos] => 9_1
            [tbl_id] => 20
            [sub_id] => ch
            [sub_name] => Chemistry
        )

)

如何删除开头的数组？谢谢。

Answer 1

$array = [
    [
        'pos' => '1_1',
        'tbl_id' => 16,
        'sub_id' => 'ch',
        'sub_name' => 'Chemistry'
    ]
];


$result = [];
foreach ($array as $data) {
    $values = array_values($data);

    $result[$data['pos']] = $values;
}

这将为您提供想要的东西。

Array
(
    [1_1] => Array
        (
            [0] => 1_1
            [1] => 16
            [2] => ch
            [3] => Chemistry
        )

)
