PHP Last Update

This piece of code generates a last updated message. It iterates through the directory and finds the newest file with a PHP file extension


<?
  // open directory
  $myDirectory = opendir(".");

  $Newest = 0;

  // get each entry
  while($entryName = readdir($myDirectory))
  {
        if(strpos($entryName, ".php") > 0)
    {
      $Newest = max($Newest, filemtime($entryName));
    }
  }

  print("<div CLASS=Footer>Site updated ");
  print(date("jS M Y", $Newest));
  print("</div>");

  // close directory
  closedir($myDirectory);
?>
