     left: 10px;
     top: 38px;
     text-align: center;
    }
    .blocks {
     background: #EEE;
     border: 1px solid #CCC;
     margin: 1px;
     height: 20px;
     width: 10px;

     z-index:11;
     left: 12px;
     top: 38px;
     filter: alpha(opacity=50);
     -moz-opacity: 0.5;
     opacity: 0.5;
     -khtml-opacity: .5
    }
    -->
    </style>
    </head>
    <body>
    <?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);
    }
    ob_end_flush();
    ?>
    <div class="percents" style="z-index:12">Done.</div>
    </body>
    </html>
