将元素动态添加到多维关联数组 - Dynamic add element to multidimensional associative array

Dynamic add element to multidimensional associative array

我正在尝试将新元素插入到类似的多维关联数组中

$arr=array('ID' => 123,
           'name' => 'rock',
           'accountID' => 'u0777f7f-77f7-4d2e-9h7c-ea775d052785',
           'admin' => array  (
                       'main' => array (
                                   'stats' =>'', 
                                   'emails' =>'', 
                                   'calls' => ''
                                )
                         )
            );
 $list='';
 $list .="['admin']['main']['hello']";
 $arr{$list}='world';
 print_r($arr);

但新元素并没有被添加到[‘admin’][‘main’]中，相反，它正在创建像这样的新数组元素

Array
(
    [ID] => 123
    [name] => rock
    [accountID] => u0777f7f-77f7-4d2e-9h7c-ea775d052785
    [admin] => Array
        (
            [main] => Array
                (
                    [stats] => 
                    [emails] => 
                    [calls] => 
                )
        )
   [['admin']['main']['hello']] => world
)

请帮我解决它。感谢

这就是您应该做的：

$arr['admin']['main']['hello'] = > 'world';

或

$main = $arr['admin']['main'];
$main['hello'] = 'world';

[['admin']['main']['hello']] => world

这是因为STRING考虑了$list

尝试更改此行

$list='';
$list .="['admin']['main']['hello']"; 
$arr{$list}='world';
print_r($arr);

带有

$list = array();
$list['main']['hello'] = "world";
$arr['admin'] = $list;
print_r($arr);

魔法将会显现。lol

如果你想要$arr类：

Array ( 
     [ID] => 123 
     [name] => rock 
     [accountID] => u0777f7f-77f7-4d2e-9h7c-ea775d052785 
     [admin] => Array ( 
                    [main] => Array ( 
                         [stats] => 
                         [emails] => 
                         [calls] => 
                                    ) 
                       ) 
     [hello] => world 
      )

您可以逻辑地编写

$arr = array();
$arr['ID'] = 123;
$arr['name'] = "rock";
$arr['accountID'] = "u0777f7f-77f7-4d2e-9h7c-ea775d052785";
$arr['admin']['main']['stats'] = "complete";
$arr['admin']['main']['emails'] = "example@email.com";
$arr['admin']['main']['calls'] = "yourfunction";
$arr['hello'] = "world";
