Bootstrap pagination

Bootstrap Pagination with MySQL Data

This PHP script connects to a MySQL database, retrieves a list of top movies from a top_100_movies table, and displays them one at a time with pagination controls. It calculates which movie to show based on the current page ($_GET['page']) and generates a responsive pagination bar using Bootstrap-style classes, allowing users to navigate through pages of movie data sorted by popularity.

Demo
Captain America: Civil War (2016)
Following the events of Age of Ultron, the collective governments of the world pass an act designed to regulate all superhuman activity. This polarizes opinion amongst the Avengers, causing two factions to side with Iron Man or Captain America, which causes an epic battle between former allies.
