title: Comma separated list from array
body: <p>I am wondering how to:  </p>
  
  <ul>
  <li>Make comma-separated list</li>
  <li>Strip last comma from list</li>
  </ul>
  
  <p>Here's an array example:</p>
  
  <pre><code>Array
  (
      [name] =&gt; Array
          (
              [0] =&gt; Some message to display1
          )
      [test] =&gt; Array
          (
              [0] =&gt; Some message to display2
          )
      [kudos] =&gt; Array
          (
              [0] =&gt; Some message to display3
          )
  
  )
  </code></pre>
  
  <p>I want to display it like this:</p>
  
  <p><strong>Comma-List:</strong> <code>Some message to display1, Some message to display2, Some message to display3</code></p>
