Let's assume you have another variable holding data, then your index method should look like:

Access content of $post as $post->id instead of $post->$id

 public function index(){
     $posts = Post::all();
     $someData = []; // extra variable
     return view('posts.index',compact('posts','someData'));
 }

Another Change to be made is in view file: On a side note: you don't have to use traditional PHP tags and foreach, instead you could use Laravel's clean and elegant method like following:

Replace your block of code:

<?php 
   foreach ($posts as $post) {
      echo "<li><a href = 'post/$post->$id'>".$post->$title."</a></li>";
   }
?>

Updated code:

@foreach($posts as $post)
    <li><a href = "{{ url('post/'. $post->id) }}" </a></li>
@endforeach

Change view to

</head>
<body>
<ul>
    <?php 
        foreach ($posts as $post) {
        echo "<li><a href = 'post/$post->id'>".$post->title."</a></li>";
        }
    ?>
</ul>
</body>
</html>

Change $post->$id to $post->id and $post->$title to $post->title Also compact($posts) to compact('posts') and compact($post) to compact('post')
