This also works the same, for comparisons sake, but your solution
benchmarks faster:
$i=2;
$fp = fopen($url,'r');
$file = fread($fp,filesize($url));
$file = highlight_string($file,TRUE);
$file = str_replace('<code>','<code><span
style="color:black;">00001</span>',$file);
$file = preg_replace('/<br \/>/e','sprintf("<br /><span
style=\"color:black;\">%05d </span>",$i++)',$file);
echo "<hr>";
echo $file;
Enjoy!
