Are there any free PHP libraries/utility functions that can color the syntax of
various programming languages (eg. Java and C++)?

I am posting code snippets on my site and would like to know if there is a way
to easily give them syntax highlighting automatically.

Thanks!

There is a PEAR class Text_Highlighter which provides a framework in
which XML based files per language are parsed to highlight code. Not
sure if someone has already build the XML files for the languages you
are looking for. May Google be your best friend!

GeSHi and PEAR Text_Highlighter each cover plenty of languages. There's
significant overlap between them; when a language is covered by both, the
Text_Highlighter output is usually a bit nicer.

Take a look at my demitextile class <http://demiblog.org/etc/demitextile/>.
It combines syntax highlighting (via GeSHi, Text_Highlighter and some
built-in) with smart quotes and the Textile markup language
<http://textism.com/tools/textile/>.

Example:
http://examples.tobyinkster.co.uk/demitextile-usage1
http://examples.tobyinkster.co.uk/demitextile-output1

Note that it's smart enough to detect when you've embedded CSS, Javascript
and PHP within some HTML, and switches syntax highlighting mode
accordingly.

Thanks very much, I'll see if that helps me.

I tried using Google, but it's really tricky to search for some terms.
Apparently, coloring the syntax of *PHP* scripts in *Java* applications is a far
more common task than the other way around, so "syntax+color+php+java" isn't
exactly helpful. ;)

I've tryed Text_Hilighter before, seemed to be the 1 and only PEAR
extension that I've had trouble with, I'm not however, ruling out the
fact it could have been the dodgey gentoo vserver i'm running that
particular website under... I was just getting a silly error that the
actual highlight function wasn't recognized, however the factory
function was. tt.

Good luck

Designed for PHP4, written in 2002, perhaps still a good starting point...

I've managed to get Text_Highlighter to work (and even made a new XML
description for a scripting language, which it generated a highlighting class
from). It works very well, thanks!

You can use http://softwaremaniacs.org/soft/highlight/en/
That's very easy to use library and it don't need PHP. You just drop
few lines of JavaScript on your page and it's work.

But between a Javascript and a PHP solution, I'd say server-side is the
more desirable. After all, my CMS (Drupal) can cache the filter output
of the PHP function, and therefore has minimal resource use, compared to
forcing every user to run the parser in their browser.

Not to speak of browser compatibility and accessibility, of course...

This is not exactly what you asked for

http://www.gnu.org/software/src-highlite/

but in the near future I want to extend it in order to generate php
highlighter so you might want to keep an eye on it :-)
