PHP Laminas Framework Flash Messenger 将空格替换为“+”

Question

flash messenger 在尝试创建某些内容时会用“+”符号替换消息空间，但在更新时它可以完美运行。

如何去掉“+”符号？

创建代码

            // success
            $text = $this->translate('The group %s has been created successfully.');
            $message['success'] = sprintf($text, $group['name']);
            $cookie = new SetCookie('newGroup', $group['name'], time() + 30, '/');
            $this->getResponse()->getHeaders()->addHeader($cookie);
            if (isset($post['isAPIData']) && $post['isAPIData'] == 1) {
                $isAPIResponse = 1;
            } else {
                if (!$request->isXmlHttpRequest()) {
                    $this->flashMessenger()->addSuccessMessage($message['success']);
                    return $this->redirect()->refresh();
                }
            }

更新代码

            // success
            $text = $this->translate('The group %s has been updated successfully.');
            $message['success'] = sprintf($text, $group['name']);
            if (isset($post['isAPIData']) && $post['isAPIData'] == 1) {
                $isAPIResponse = 1;
                return [
                    'message'  => $message,
                    'isAPIResponse' => $isAPIResponse
                ];
            } else {
                if (!$request->isXmlHttpRequest()) {
                    $this->flashMessenger()->addSuccessMessage($message['success']);
                    $this->redirect()->refresh();
                }
            }

当var_dump($message['success'])输出正确时

如何解决这个问题？
