title: How to check if a Laravel Collection is empty?
body: <p>I create a view by doing an eloquent query and then pass it over to Blade.</p>
  
  <pre><code>@if($contacts != null)
  //display contacts
  @else
  You dont have contacts
  @endif
  </code></pre>
  
  <p>However it always assume that $contacts has something even if the query gives me nothing.</p>
  
  <p>I did <code>dd($contacts)</code> and get: </p>
  
  <pre><code>Collection {#247 ▼
    #items: []
  }
  </code></pre>
  
  <p>How do I check if it is empty?</p>
