I wrote a piece of project planning code - to generate GANT charts in PHP - when we were planning all the works on Well House Manor the best part of 2 years ago now. And although I did little more that provide a screen capture here on "The Horse's Mouth", one of our popular hits has turned out to be that page.
So I've looked through the code and realised that I can publish it, and the sample data - and indeed I can have a running copy on our web server. So here you are:
Example Gant chart (PHP)
Source code for Gant Chart program
Sample Data file
Techniques such as these are covered on our new PHP Techniques course (written 2008-05-03, updated 2008-05-04)
