This line will always cause your function to return 2
static $line = 1;
One solution is to use a second parameter to reset the counter like this:
function addPrefix( $matches, $reset=False )
{
static $line;
if(!$reset) return $line++ . $matches[0];
else $line = 0;
}
$url = split("\?", $_GET['url']);
//reset counter
addPrefix('',True);
$source = highlight_file($url[0], true);
The regex I'll leave to others :)
