Osticket部门电子邮件ID

我想获取ost_department email_id我使用了以下方法

$args1 = array( 'username'        => $this->osticket->username,
                'password'        => $this->osticket->password,
                'departmentId'    => $dept->id
              );
try { 
    $getmail = $osticket->__call('ostDepartment.getInfo',$args1); 
    echo '<pre>', print_r($getmail);exit;
} catch(SoapFault $e) {
    $error  = true;
}

这是我的回波的输出

    [id] => 3
    [name] => bcod
    [email] => Support
    [isPublic] => 1
)
