从php对象中获取特定数据

结合使用office365帐户，我需要检索发送电子邮件的电子邮件地址

要检索，我使用：

$message->getFrom()

但结果是：

Ddeboer\Imap\Message\EmailAddress Object
(
    [mailbox:Ddeboer\Imap\Message\EmailAddress:private] => my
    [hostname:Ddeboer\Imap\Message\EmailAddress:private] => email.com
    [name:Ddeboer\Imap\Message\EmailAddress:private] => Full Name
    [address:Ddeboer\Imap\Message\EmailAddress:private] => my@email.com
)

如何仅检索此对象中我需要的最后一部分my@email.com

$message->getFrom()->getAddress()
