Question

尝试创建新帖子时遇到这些错误：

Route.php第280行中的2/2 ReflectionException：   App \ Http \ Controllers \ PostController类不存在
     PostController.php第70行中的
1/2 FatalThrowableError：   解析错误：语法错误，意外的“会话”（T_STRING）

一切正常，直到我在store()方法中添加以下代码行：

$post->tags()->sync($request->tags, false);

这是我的控制人

<?php

   {
      $categories = Category::pluck('name', 'id');
      $tags = Tag::pluck('name', 'id');
      return view('posts.create', compact('categories', 'tags'));
   }

   public function store(Request $request)

您有一个看不见的角色：

$post->tags()->sync($request->tags, false);<feff>

如果您的编辑器可以查看不可打印的字符，则可能会显示类似这样的字符。
