title: Calling other function in the same controller?
body: <p>I've this controller, and the <code>function read($q)</code> return error <code>Call to undefined function sendRequest()</code></p>
  
  <pre><code>&lt;?php
  
  class InstagramController extends BaseController {
  
  /*

  | Default Home Controller

  | You may wish to use controllers instead of, or in addition to, Closure
  | based routes. That's great! Here is an example controller method to
  | get you started. To route to this controller, just add the route:
  |
  |   Route::get('/', 'HomeController@showWelcome');

  public function read($q)
  {
      $client_id = 'ea7bee895ef34ed08eacad639f515897';
  
      $uri = 'https://api.instagram.com/v1/tags/'.$q.'/media/recent?client_id='.$client_id;
      return sendRequest($uri);
  }
  
  public function sendRequest($uri){
      $curl = curl_init($uri);
      curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
      curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
      curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
      $response = curl_exec($curl);
      curl_close($curl);
      return $response;
  }
  
  }
  </code></pre>
  
  <p>I'm assuming it's because I'm referencing the function in the wrong manner, but I can't find any explanations for how to do it.</p>
