RE: [PHP] Re: Q. Adding line numbers to highlighted source

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! ---John W.
