如何删除数组的键名中的空格在PHP？ [英] How to remove spaces in array keys names in php?

问题描述

我想删除数组的键名的所有空间，即str_replace函数（''，''，$值）

I am trying to remove all spaces in array keys names i.e. str_replace(' ','',$value) (or worst cast scenario replace them with underscores (_) )

和我想在我多维数组的最深层次（如下图所示）（因为其他层/水平没有空格（感谢上帝！））

and I am trying to do this at the deepest level (shown below) of my multidimensional array (because other layers/levels don't have spaces (THANK GOD!))

[ownPagestoriesbystorytype] => Array
                        (
                            [type] => pagestoriesbystorytype
                            [object_id] => 12365478954
                            [metric] => page_stories_by_story_type
                            [end_time] => 1386057600
                            [period] => 86400
                            [ownValues] => Array
                                (
                                    [type] => pagestoriesbystorytypemetrics
                                    [fan] => 1913
                                    [page post] => 153
                                    [user post] => 24
                                )

                        )

                    [ownPagestorytellersbystorytype] => Array
                        (
                            [type] => pagestorytellersbystorytype
                            [object_id] => 12365478954
                            [metric] => page_storytellers_by_story_type
                            [end_time] => 1386057600
                            [period] => 86400
                            [ownValues] => Array
                                (
                                    [type] => pagestorytellersbystorytypemetrics
                                    [fan] => 1902
                                    [page post] => 137
                                    [user post] => 9
                                )

                        )

到目前为止，我尝试都石沉大海：

So far my attempts have been fruitless :

[...]
if (is_array($value))
        {

            $keys = str_replace(' ','',array_keys($value));
            $values = array_values($value);
            $value = array_combine($keys,$values);
        }
[...]


[...]

foreach ($value as $k => $v)
            {
                $b = str_replace(' ','',$k);
                $value[$b] = $value[$k];
                unset ($value[$k]);

            }

[...]

在codeS以上不工作，但是如果我把的print_r（$值）;在循环结束时，你可以清楚地看到，空间被删除，不知怎么竟最终的结果结束了空间（STILL）。

The codes above do not work, however if I put print_r($value); at the end of the loop you can clearly see that spaces are being removed, just somehow the end result ends up being with spaces (STILL).

整个循环看起来是这样的：

The whole loop looks like this:

for ($i=0;$i<count($results);$i++)
{

    for ($j=0;$j<count($results[$i]);$j++)
    {
    foreach($results[$i][$j] as $key => $value)
    {
        $typee = ['type' => strtolower(str_replace('_','',$results[$i][$j]['metric']))];
        array_insert($results[$i][$j],$typee,0);
        if (is_array($value))
        {

            $keys = str_replace(' ','',array_keys($value));
            $values = array_values($value);
            $value = array_combine($keys,$values);

            $type = ['type' => strtolower(str_replace('_','',$results[$i][$j]['metric']))."metrics"];
            array_insert($results[$i][$j]['value'],$type,0);
            $results[$i][$j]['ownValues'] = $results[$i][$j][$key];
            unset($results[$i][$j][$key]);


        }
    }
    }
}

你可以看到整个阵列的样子在这里：

And you can see how the whole array looks like here:

有什么建议？ ：）

推荐答案

这将帮助：

function fixArrayKey(&$arr)
{
    $arr = array_combine(
        array_map(
            function ($str) {
                return str_replace(" ", "_", $str);
            },
            array_keys($arr)
        ),
        array_values($arr)
    );

    foreach ($arr as $key => $val) {
        if (is_array($val)) {
            fixArrayKey($arr[$key]);
        }
    }
}

如下测试：

$data = array (
    "key 1" => "abc",
    "key 2" => array ("sub 1" => "abc", "sub 2" => "def"),
    "key 3" => "ghi"
);
print_r($data);
fixArrayKey($data);
print_r($data);

输入：

Array
(
    [key 1] => abc
    [key 2] => Array
        (
            [sub 1] => abc
            [sub 2] => def
        )

    [key 3] => ghi
)

输出：

Array
(
    [key_1] => abc
    [key_2] => Array
        (
            [sub_1] => abc
            [sub_2] => def
        )

    [key_3] => ghi
)
