title: Delete files older than specific month
body: <p>I create that script:</p>
  
  <pre><code>$zips = glob("*.zip");
  
  usort($zips, function($a, $b) { return filemtime($a) - filemtime($b); });
  
  $dateFile = date("F d Y H:i:s", filectime($zips[0]));
  $dateNow = date("F d Y H:i:s");
  
  echo "dateFile = " . $dateFile;
  echo "&lt;br /&gt;";
  echo "dateNow = " . $dateNow
  </code></pre>
  
  <p>Output is:</p>
  
  <pre><code>dateFile = August 03 2017 10:23:47
  dateNow = August 03 2017 10:43:27
  </code></pre>
