</head>
<body>
<&#63;php
if (ob_get_level() == 0) {
  ob_start();
}
echo str_pad('Loading... ',4096)."<br />\n";
for ($i = 0; $i < 25; $i++) {
  $d = $d + 11;
  $m=$d+10;
  //This div will show loading percents
  echo '<div class="percents">' . $i*4 . '% complete</div>';
  //This div will show progress bar
  echo '<div class="blocks" style="left: '.$d.'px"> </div>';
  flush();
  ob_flush();
  sleep(1);
