title: How to check if a file exists in Laravel 5.2
body: <p>I have tried the following method to check if file exist:</p>
  
  <pre><code>@if(file_exists(public_path('/user_img/'.Auth::user()-&gt;id.'.jpg')))
  </code></pre>
  
  <p>It returns <code>false</code> even when the file exists!</p>
  
  <p>What is wrong with it?</p>
