PHP Simple Source Highlighter
The simple source highlighter is a simple php include that will turn a string containing C/C++, PHP or Bash script source into colourized, syntax highlighted versions of the same.
This code isn't particularly pretty or complete, but it works and it's simple to integrate if you quickly want to generate html examples of your source.
To be completely upfront, this code isn't particularly bright. Escaped characters will screw up the highlighting (where they effect things like quotes) and complex structures are likely to be displayed wrong. If you want a robust and efficient syntax highlighter, move along. :)
