When printing off source code there is a handy function that will parse the code and produce nice looking syntax highlighted code. There are actually two functions you can use. The highlight_string() function takes a string as a parameter and will print the highlighted code.

For now I will concentrate on the highlight_string() function, but the output of these two functions is the same.
