PHP bot to get wikipedia definitions

 / Published in: PHP
 

URL: http://www.barattalo.it/2010/08/29/php-bot-to-get-wikipedia-definitions/

If you need to add some content to your pages without having that content in your database you can use Wikipedia API. You can, for example, need to add automatically a simple description to a city name, or to a band name. Or you could need to add the definition of some technological terms. You can do all of this things using Wikipedia, since Wikipedia has an API that easily lets you do it.
