title: Getting All $_POST From Multiple Select Value
body: <p>I have this HTML code :</p>
  
  <pre><code>&lt;select name="cars"&gt;
    &lt;option value="volvo"&gt;Volvo&lt;/option&gt;
    &lt;option value="saab"&gt;Saab&lt;/option&gt;
    &lt;option value="opel"&gt;Opel&lt;/option&gt;
    &lt;option value="audi"&gt;Audi&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>and to make user able to select more than one items, I'm using this jQuery plugin : <a href="http://harvesthq.github.com/chosen/">http://harvesthq.github.com/chosen/</a></p>
  
  <p>but, once it submitted... the PHP script only able to retrieve one of <code>$_POST['cars']</code> value. the last one. how to make PHP to be able to retrieve ALL of it?</p>
