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();
