Description:
------------
I would find highlight_file much more useful, particularly for writing on-line tutorials, articles, etc if it would take a line number and count optional arguments, to print out only an excerpt of the file.

One could then intersperse bits of code and commentary very easily with original source files instead of having to keep code snippets in sync as you develop/author an article.

One can, of course, play games with explode("<br />" and array_slice, but it's a bit of a pain, really.

It would also be extra nifty if line numbers could be added on the left with yet another optional arg, and maybe even an arg for absolute|relative numbering for the snippets.

PHP Rocks!

highlight_file is a small helper and not meant to be a full-features highlighter.

Instead of parsing the output you might also read the file (using file(), file_Get_contents() or so and then use highlight_string() on some chunks of it.
