与Laravel语法错误混淆：意外的'。 （对我来说似乎不错）

Posted 2023-01-15

我是Laravel的新手。

我一直收到此语法错误：

Symfony\Component\Debug\Exception\FatalThrowableError
syntax error, unexpected '.' 

相关行是这样：

  $post = .\DB::table('posts')->where('slug', $slug)->first();

这是整个无效的代码：

<?php

namespace App\Http\Controllers;

class PostsController extends Controller


  public function show($slug)
  
    $post = .\DB::table('posts')->where('slug', $slug)->first();

    dd($post);

     // This was to simulate a database
     // $posts = [
     //   'my-first-post' => 'Hello This is my first blog post',
     //   'my-second-post' => 'Hello This is my second blog post',
     // ];

     // if it doesn't exist then throw this error:
     if (! array_key_exists($post, $posts))
       abort(404, 'Sorry, that post was not found.');
     

     // return this view:
      return view('post', [
        'post' => $posts[$post]
      ]);
  

我在这里想念的是什么！？

谢谢

答案

更改此行

  $post = DB::table('posts')->where('slug', $slug)->first();
