figlet tool / display ascii art to html/webpage

I'd like to use the figlet command line tool to input text into figlet, then process the output to html.

** note ** figlet processes text into ascii art **

Is there an easiest method to do this? Should I just try php exec? Or what it be easier/better/cleaner/safer etc with python or ruby/camping or node.js or whatever else?

Thanks for any suggetions.
