title: What is the "@" Symbol for in Comments?
body: <p>In PHP, I've noticed people put the "@" symbol in source code comments. One great example is anything WordPress. When you look at the source, you see things like </p>
  
  <pre><code>/** Results of the last query made
   *
   * @since 1.0.0
   * @access private
   * @var array|null
   */
  var $last_result
  </code></pre>
  
  <p>(wp-db.php, Line 124)</p>
  
  <p>It changes the syntax highlighting in my editor so I'm assuming it does something, but I'm not sure what it does. Would someone explain what the "@" symbol does in comments?</p>
