Frequently Asked Questions

Code

What code is available?

All the code is available in the download area, so have a look in there. Some more notable items are:

Will you write code that does X?

Unlikely, though there's no harm in trying.

Licensing

What's the license of the code?

The code I write is covered by the PHPGuru license, which you can read here. A summary is that there is a small license fee to pay, and there's a discounted fee if you're a charity or educational institute. The license entitles you to use the code as you wish, includes the HTML5 RGraph library and also covers anything I may write in the future.

Do I have to pay for this code?

Yes you do - the code I write is not free.

Miscellaneous

How did you do the download area?

A combination of things:

  1. A PHP script which outputs the HTML header to a file. This is done by calling a script on the website and automated using cron and wget. The same script also generates the footer.
  2. This file is then read by Apache using the HeaderFile directive inside a .htaccess file in the /downloads/ directory. The footer file is drawn in using the ReadmeName directive.

Bearing in mind my sight isn't good, it looks OK to me... :)

If you're interested in web development, then you may also be interested in RGraph: HTML5 canvas graph library. It uses HTML5 features to produce a wide variety of graph types. Because it moves the creation of graphs from the server to the client, it can significantly reduce the load on your server and your bandwidth usage.
