如何将数组转换为另一种形式？

  • 772

有这样一个数组

Array
(
    [0] => Array
        (
            [content] => 12
            [id] => tab-about-1
            [name] => Описание 1
        )

    [1] => Array
        (
            [content] => 13
            [id] => tab-about-2
            [name] => Описание 2
        )

    [2] => Array
        (
            [content] => 14
            [id] => tab-service
            [name] => Описание 3
        )

    [3] => Array
        (
            [content] => 15
            [id] => tab-service-1
            [name] => Описание 4
        )
)

如何将其转换为：

Array
(
    [about] => Array
        (
            [0] => Array
                (
                    [content] => 12
                    [id] => tab-about-1
                    [name] => Описание 1
                )
            [1] => Array
                (
                    [content] => 13
                    [id] => tab-about-2
                    [name] => Описание 2
                )
        )

    [service] => Array
        (
            [0] => Array
                (
                    [content] => 14
                    [id] => tab-service
                    [name] => Описание 3
                )

            [1] => Array
                (
                    [content] => 15
                    [id] => tab-service-1
                    [name] => Описание 4
                )
        )
)

据我了解，您需要使用正则表达式过滤所有内容吗？

php

  1. 您可以不使用正则表达式，如下所示：

    $result = [];
foreach ($data as $row) {
    [, $id] = explode('-', $row['id']);

    if ($id) {
        $result[$id][] = $row;
    }
}

    像这样，是的。

    $result = [];
foreach($data as $d){
    preg_match('/tab-([^-]*)/', $d['id'], $matches);

    $key = $matches[1];

    if(!array_key_exists($key, $result)) $result[$key] = [];
    $result[$key][] = $d;
}

print_r($result);
