Question

我有以下数组。我想动态更新这个数组。

Array
(
[0] => Array
    (
        [id] =>
        [cip] => 172.35.2.45
        [ctime] => 1498718978
        [uip] => 172.35.2.40
        [utime] => 1498712478
        [interface] => wan
        [type] => pass
        [disabled] => no
    )
[1] => Array
    (
        [id] =>
        [cip] => 172.35.2.24
        [ctime] => 1498778578
        [uip] => 172.35.2.41
        [utime] => 1498532478
        [interface] => wan
        [type] => pass
        [disabled] => no
    )
)

我希望它转换成。

Array
(
[0] => Array
    (
        [id] =>
        updated => Array
        (
            [time] => 1498712478
            [username] => admin@172.35.2.40
        )
        created => Array
        (
            [time] => 1498712478
            [username] => admin@172.35.2.45
        )
        [interface] => wan
        [type] => pass
        [disabled] => no
    )
[1] => Array
    (
        [id] =>
        [updated] => Array
        (
            [time] => 1498532478
            [username] => admin@172.35.2.41
        )
        created => Array
        (
            [time] => 1498778578
            [username] => admin@172.35.2.24
        )
        [interface] => wan
        [type] => pass
        [disabled] => no
    )
)

这里我们在主数组中有两个元素，它可以非常，我尝试使用foreach循环和其他一些东西。但我不想接近我想要的答案请帮助我排序这个

Answer 1

想想我会将我的评论转换成答案，因为如果没有适当的缩进，它会很长且不守规矩。 false是原始数组

$array1

这基本上只是逐行排列第二个数组，并根据你的问题正确设置数组元素。

我确信有一种方法可以自动完成您要尝试的操作，因此您不必逐行进行，但老实说，任何自动执行此步骤的答案都是过度的，并且肯定会花费更多时间来处理比这个。

Answer 2

使用array_combine和unset函数的简短解决方案：

// $arr is your initial array
$arr['updated'] = array_combine(['time', 'username'], [$arr['utime'], 'admin@' . $arr['uip']]);
$arr['created'] = array_combine(['time', 'username'], [$arr['ctime'], 'admin@' . $arr['cip']]);
unset($arr['utime'], $arr['ctime'], $arr['uip'], $arr['cip']);

print_r($arr);

输出：

Array
(
    [id] => 
    [interface] => wan
    [type] => pass
    [disabled] => no
    [updated] => Array
        (
            [time] => 1498712478
            [username] => admin@172.35.2.40
        )

    [created] => Array
        (
            [time] => 1498718978
            [username] => admin@172.35.2.45
        )
)

Answer 3

我认为最干净的选择是这样的：

$array2 = [
        'id => '',
        'updated' => [
            'time' => $array1['utime'],
            'username' => $array1['username']
        ],
        'created' => [
            'time' => $array1['ctime'],
            'username' => $array1['username']
        ],
        'interface' => $array1['wan'],
        'type' => $array1['pass'],
        'disabled' => $array1['no']
    ]
];

您没有说明PHP版本，因此我使用方括号来启动数组，如果您仍然在7以下，则需要将所有方括号替换为array（）; < / p>

Answer 4

我假设你的起始数组中有多个条目，并且想要从更大的初始数组中构建结果数组，所以我把它放在一个循环中。

$array1[] = array(
        'id' => '',
        'cip' => '172.35.2.45',
        'ctime' => 1498718978,
        'uip' => '172.35.2.40',
        'utime' => 1498712478,
        'interface' => 'wan',
        'type' => 'pass',
        'disabled' => 'no'
    );

$array2 = array();
$directkeys = array('id', 'interface', 'type', 'disabled');
foreach ($array1 as $mk => $subarray){
    foreach($subarray as $k => $v){
        if(in_array($k, $directkeys)) $array2[$mk][$k] = $v;
        if($k == 'uip') $array2[$mk]['id']['updated']['username'] = 'admin@'.$v;
        if($k == 'utime') $array2[$mk]['id']['updated']['time'] = $v;
        if($k == 'cip') $array2[$mk]['id']['created']['username'] = 'admin@'.$v;
        if($k == 'ctime') $array2[$mk]['id']['created']['time'] = $v;    
    }
}

输出是：

[0] => Array
    (
        [id] => Array
            (
                [created] => Array
                    (
                        [username] => admin@172.35.2.45
                        [time] => 1498718978
                    )

                [updated] => Array
                    (
                        [username] => admin@172.35.2.40
                        [time] => 1498712478
                    )

            )

        [interface] => wan
        [type] => pass
        [disabled] => no
    )

Answer 5

这是通过这样做完成的。

foreach($oldarray as $key => $value){
    $newarray['created']['time'] = '"'.strtotime($value['ctime']).'"';
    $newarray['created']['username'] = 'admin@'.$value['cip'];
    $newarray['updated']['time'] = '"'.strtotime($value['utime']).'"';
    $newarray['updated']['username'] = 'admin@'.$value['uip'];
}

将数组转换为关联数组
