title: Get POST variable that is an array
body: <p>All,</p>
  
  <p>I have the following hidden variables:</p>
  
  <pre><code>&lt;input type="hidden" name="chk[10]" value = "cats"&gt;
  &lt;input type="hidden" name="chk[13]" value = "dogs"&gt;
  &lt;input type="hidden" name="chk[14]" value = "fish"&gt;
  </code></pre>
  
  <p>I want to get these variables through POST and print them. How can I do this in PHP?</p>
  
  <p>Thanks</p>
