title: How to handle multiple checkboxes in a PHP form?
body: <p>I have multiple checkboxes on my form:</p>
  
  <pre><code>&lt;input type="checkbox" name="animal" value="Cat" /&gt;
  &lt;input type="checkbox" name="animal" value="Dog" /&gt;
  &lt;input type="checkbox" name="animal" value="Bear" /&gt;
  </code></pre>
  
  <p>If I check all three and hit submit, with the following code in the PHP script:</p>
  
  <pre><code>if(isset($_POST['submit']) {
     echo $_POST['animal'];
  }
  </code></pre>
  
  <p>I get "Bear", i.e. the last chosen checkbox value even though I picked all three. How to get all 3?</p>
