我有多个 cpanel 帐户，我想使用 RoundCube 的密码更改插件。在插件的 config.inc.php 文件中（如下所示），我包含了一个用于设置配置变量的函数，它整合了代码（请参阅 case 语句了解我的意思）。
我试过返回函数数组、添加全局变量等等。对于我的死亡，我无法让密码插件了解变量已配置。我将结果打印到 switch 语句内的日志文件中（在某一时刻），它返回了函数内定义的每个变量。但是，由于某种原因，插件没有在 password.php 文件中获取这些变量。
用户端的结果是密码更改失败并显示错误消息。

$rcmail_config['password_driver'] = 'cpanel';

function getDomainFromEmail($email)
{
$domain = substr(strrchr($email, "@"), 1);
return $domain;
}
