title: install cURL on a virtual machine (virtualbox)
body: <p>I want to make stress tests on a virtual machine, I want to test the response time for a twitter request but when I try to access the page i'm getting the following error:</p>
  
  <pre><code>Fatal error: Uncaught exception 'Exception' with message 'You need to install cURL, see: http://curl.haxx.se/docs/install.html' in /var/www/assignment2/old_app/TwitterAPIExchange.php:37 Stack trace: #0 /var/www/assignment2/old_app/twt.php(33): TwitterAPIExchange-&gt;__construct(Array) #1 {main} thrown in /var/www/assignment2/old_app/TwitterAPIExchange.php on line 37
  </code></pre>
  
  <p>how do I install cURL on a virtual machine? 
  this code is originally hosted in a hosting server therefore I never had to make any installations...</p>
