title: better PHP variable equals itself
body: <p>In PHP, is there a better way to say a variable equals itself, example:</p>
  
  <pre><code>$floor = floor($difference / $key);
  if($floor &gt; 1) {
      $value .= "s";
  } else {
      $value .= "";
  };
  </code></pre>
  
  <p>On the fourth line, we're saying <code>$floor</code> equals itself plus an empty string. Is there a better way to do this?</p>
