title: Getting array keys in Twig? (Symfony)
body: <p>Is it possible to get the key of an array in Twig (in Symfony)?</p>
  
  <p>For example if I have an array of:</p>
  
  <pre><code>array(
  'key1' =&gt; 'value1',
  'key2' =&gt; 'value2',
  );
  </code></pre>
  
  <p>Is it possible in Twig to print: </p>
  
  <blockquote>
    <p>key1: value1 </p>
    
    <p>key2: value2</p>
  </blockquote>
  
  <p>Thanks</p>
