提交时显示语法错误的 yii2 表单

问：

在表单模型中，我遇到了以下错误：

PHP 解析错误 – yii\base\ErrorException 语法错误、意外的“public”（T_STRING）、期望函数（T_FUNCTION）

在互联网上检查了它的解决方案，并检查了我的代码，在那里我找不到任何语法错误。 在我的模型代码中：

<?php

namespace app\models;

use Yii;

use yii\base\Model;

class Contact extends \yii\db\ActiveRecord{

   public static function tableName()

   {

       return 'contact';

   }


   public function rules()

   {

       return [

           [['name','email','message'], 'required'],

           ['email', 'email'],

           [['name'],'string', 'max' => 50],

           [['email'], 'string', 'max' => 50],

           [['message'], 'string', 'max' => 255],

          

       ];

   }

}
?>

这是我的控制器代码：

<?php
namespace frontend\controllers;

use app\models\Contact;

use Yii;
use yii\base\InvalidParamException;
use yii\web\BadRequestHttpException;
use yii\web\Controller;
use yii\filters\VerbFilter;
use yii\filters\AccessControl;
use common\models\LoginForm;
use frontend\models\PasswordResetRequestForm;
use frontend\models\ResetPasswordForm;
use frontend\models\SignupForm;
use frontend\models\ContactForm;

以下是查看代码：

$this->title = 'Contact Form';

?>
