array_merge_recursive 和整数键

Question

我用换行符分隔文本

/EXT/123/SOMEPARAM:VALUE123
/EXT/123/other:VALUE222

我创建了一些代码来创建带有孩子的数组。

array_merge_recursive 如果键是数字，则数组不正确，我添加 @ 符号，结果是正确的

$astdb_array=explode("\n", $astdb_raw);

$db_data = []; $result=[];
foreach($astdb_array as $db_row){

  $db_row = trim(preg_replace('/\s/', '', $db_row));
  $row_elements = explode('/', $db_row);

   if(sizeof($row_elements)>0){
       $key = array_shift($row_elements);
       #$db_data= create_array($row_elements);
       foreach(array_reverse($row_elements) as $child){

             if (strpos($child, ':') !== false) {
                [$kkey, $vval] = explode(':',$child);
                $key = [$kkey => $key = $vval];
            }else{
                    if(is_numeric($child)){
                          $key = [ '@'.$child => $key];
                    }else{
                          $key = [$child => $key];
                    }
             }
       }

   }
}
$array_result = call_user_func_array('array_merge_recursive',$db_data);
print json_encode($array_result);

函数结果

Array
(
    [EXT] => Array
        (
            [@104] => Array
                (
                    [MOBILE] => 77761587000
                    [TENANT] => customer1
                    [TRUNK] => customer1
                    [TRUNKID] => 2
                )

            [@110] => Array
                (
                    [MOBILE] => 77761587000
                    [TENANT] => customer1
                    [TENANTID] => 2
                    [TRUNK] => customer1
                    [TRUNKID] => 2
                )

        )

    [ROUTES] => Array
        (
            [@1] => Array
                (
                    [PATTERN] => 5555
                    [PERMS] => type,any,end
                )

            [@2] => Array
                (
                    [NAME] => KZ
                    [PATTERN] => _XXXXXXXXXXX
                    [PERMS] => type,any,end
                    [TYPE] => OUTDOOR
                )

        )

)

结果正确，但需要从键中删除符号@，尝试使用：

$result = array_map(function($s){return str_replace('^','',$s);}, $array_result);

这对我没有帮助。请帮忙解决这个问题.... 谢谢
