title: Increment list in PHP alphabetically
body: <p>I'm working on something where the user is generating a number of objects in a form. When they submit the form, I want to echo the results back to them in a list (very distilled summary of what I'm doing).</p>
  
  <p>In PHP, I know how to increment something in the conventional manner (1, 2, 3), but due to elements in the UI, I want to increment the list alphabetically (A, B, C). How would I do this?</p>
  
  <p>Working code incrementing the list numerically:</p>
  
  <pre><code>//LOOP THROUGH THE ARRAY OF OBJECTS PASSED TO THIS PAGE FROM THE FORM
  foreach ($waypoints as $key =&gt; $value) {
  $current = $key + 1;
      echo "&lt;p&gt;&lt;strong&gt;Waypoint #$current:&lt;/strong&gt; $value&lt;/p&gt;";
  }
  </code></pre>
