title: Laravel How to Isset _GET
body: <p>I'm still very new at Laravel. </p>
  
  <p>I got problem how can I use <code>Isset($_GET)</code>?</p>
  
  <p>How to get for example: <a href="http://virtualhost.com/flytrap/public/location?city=25" rel="nofollow">http://virtualhost.com/flytrap/public/location?city=25</a>?</p>
  
  <p>Usually when at pure PHP, I always use: </p>
  
  <pre><code>if (isset($_GET["submit"]))
  {
     $location = $_GET["city"];
  }
  </code></pre>
  
  <p>to get city value. So I can use it for query at database. If I use Core PHP method I got an error.</p>
