Based on the modular version for the pagination, now I have created a version easier to implement, using classes for PHP version 4. The implementation is simple, is necessary to include the class with a require or an include. We defined basic properties for pagination such as an amount of elements to paginate, elements by page, page to which the element "page" will be sent, you need a CSS style and finally we generate the pagination to show it.

Styles for WP-Digg style pagination plugin, Digg Style pagination Class, the modular version, and the original programed bye strangerstudios.
