How to Implement Simple PHP Pagination?

Simple PHP paging script

Paging is a technique used to display large data sets in manageable chunks, usually by dividing them into pages. In PHP, creating a simple pagination script is relatively simple and straightforward.

Method Overview

The code snippet provided combines HTML and PHP to implement pagination. It first calculates the total number of items in the database table, the number of items to display per page, and the current page number. It then calculates the offset of the database query and generates "back" and "forward" links for navigation.

Code implementation

The code snippet first uses a SQL query to get the total number of items from a database table. It then defines the number of items to be displayed per page and calculates the number of pages required. The current page number is determined using the GET parameter "page" and cleaned using filter_input.

The offset for a database query is calculated as (page number - 1) × number of items per page. Pagination information is displayed to the user, including the current page number, total number of pages, and the range of items being displayed.

Prepared statements are used to get paginated results from the database. The code iterates through the results and displays each item in paragraph form. If no result is found, the corresponding prompt message is displayed.
