php - 使用变量操作多维数组

Question

我想使用变量的值并将其分配给数组。

例如 - 此代码有效：

$mf_hook_emails[19734]['Dept Notify'] = 'customer_service@abc.com';

但是此代码不起作用（首先将电子邮件地址分配给变量）：

$deptemail='customer_service@abc.com';
$mf_hook_emails[19734]['Dept Notify'] = $deptemail;                        

Answer 1

$deptemail='customer_service@abc.com';
$mf_hook_emails[19734]['Dept Notify'] = $deptemail;  

这对我来说很好。print_r($mf_hook_emails)给出：

Array (
       [19734] => Array (
             [Dept Notify] => customer_service@abc.com
             )
      )

Answer 2

你可以这样定义它：-

 $mf_hook_emails[19734]['Dept Notify'] = (string)$deptemail;
