title: Calculate days since a timestamp?
body: <p>This one works for dates in format: 0000-00-00</p>
  
  <p>But I need a function for unix timestamp format</p>
  
  <pre><code>function dateDiff($start, $end) {
  
      $start_ts = strtotime($start);
  
      $end_ts = strtotime($end);
  
      $diff = $end_ts - $start_ts;
  
      return round($diff / 86400);
  
  }
  </code></pre>
  
  <p>Could anyone help a brother out??</p>
