title: reading array of params in RoR
body: <p>If I have URL something like below:</p>
  
  <pre><code>http://test.com?x=1&amp;x=2&amp;x=3&amp;x=4&amp;x=5&amp;x=6&amp;x=7
  </code></pre>
  
  <p>Then how can I read all "x" values?</p>
  
  <p><b> Added new comment: Thanks for all your answers. I am basically from Java and .Net background and recently started looking Ruby and Rails. Like in Java, don't we have something similar as request.getParameterValues("x");</b></p>
