title: PHP add single quotes to comma separated list
body: <p>When I implode my array I get a list that looks like this:</p>
  
  <pre><code>qwerty, QTPQ, FRQO
  </code></pre>
  
  <p>I need to add single quotes so it looks like: </p>
  
  <pre><code>'qwerty', 'QTPQ', 'FRQO'
  </code></pre>
  
  <p>Can this be done using PHP? </p>
