Wikipedia Reflection

Ever wished providing the beauty that is Wikipedia on your own website? Now you can: just include this PHP script wherever you want Wikipedia to appear!

Beware of services, e.g. WikiFetcher.com, that charge incredible fees for a very similar thing!
Wikipedia content is free as long as it is attributed, and it must remain free for ever.

The script below can be used free of any charge.

NB: It is highly recommended to temporarily cache pages fetched from Wikipedia. That will assure quicker execution, smaller bandwidth requirements, and also less load on the Wikipedia servers.

Thanks to:

• Wikipedia voluntary contributors
• David Polanco and Jim Worthen from Aeonity.com
• and many others

Future:

• It would be really cool to be able to edit Wikipedia from another site (perhaps using Ajax?)

All ideas, snippets of code, or financial support towards further development are always very welcome — just contact me.
