Pagination Script and Tutorial for PHP MySQL Programmers Paging Results
Hello fellow php codersHappy This is a pagination script and tutorial created custom for educational purposes. Spread it around to people asking about how to page out database result sets. We are using PHP, MySQL, CSS, and HTML. Very simple and jQuery Ajax could be applied to make the page changing not require refreshing of the page.

This script is accompanied by this in depth VIDEO TUTORIAL:
