how to unsort output text lines from a sorted input in php?

The following code below reads sorted text lines from a file, around 30 lines and output them in sorted lines on the computer screen. But what I would like is to output the input sorted text lines unsorted without repeating the same text lines..


while(!feof($file))
{
$myfilevalue = fgets($file);
               echo '<font size="6" color="' . random_color() . '">' . $myfilevalue . '</font>';
}

function random_color()
{
    mt_srand((double)microtime()*1000000);
    $c = '';
    while(strlen($c)<6)
    {
        $c .= sprintf("%02X", mt_rand(0, 255));
    }
    return $c;
}
fclose($file);
?>
</body>
</html>

This should work

while(!feof($file))
{
$myfilevalue[] = fgets($file);
}

if (shuffle($myfileValue)){
  foreach ($myfileValue as $v){
    echo '<font size="6" color="' . random_color() . '">' . $v . '</font>';
  }
}

thanks Marqus, also, if i wanted to display ten lines instead of all 20 lines from the shuffle, i would do this..

$display_ten_lines = 10;
$count_0 = 0;

while(!feof($file))
{
$myfilevalue[] = fgets($file);
}

if (shuffle($myfileValue)){
  foreach ($myfileValue as $v){
   if($count_0 < $display_ten_lines)
  {
    echo '<font size="6" color="' . random_color() . '">' . $v . '</font>';
    $count_0++  
}  
}
}
