Pagination<\/b> is a commonly used functionality on the data list in almost every web application. Pagination divides the data between pages to load the dynamic data faster. Generally, all the data is listed on the webpage. But when the web application handles huge data and needs to retrieve from the database, it\u2019s not a good idea to load all the records at once. It will take a long time to display all the records on a single page, and sometimes your application may hang while loading the huge amount of data. To overcome this issue, you can divide the records into pages instead of showing all at once. Pagination makes it simple to spread the records across multiple pages and makes it easier to view.<\/p>\n
PHP Pagination<\/b> allows for paging data into pages and access by links. In this tutorial, we will show how to create simple pagination in PHP with MySQL<\/b>. To make the PHP pagination script reusable, we will create a Pagination library that can be reused in multiple web projects.<\/p>\n
In this example we will create a simple web application to display the members list from the database with pagination using PHP and MySQL. Initially, it will show 9 records per page. If there are more than 9 records, it will create pagination links to access the next set of records. The user can navigate to the next or previous page by clicking on the pagination links. <\/p>\n
Before getting started, let\u2019s see the files structure of the PHP pagination example script.<\/p>\n
pagination_with_php\/<\/span>\r\n\u251c\u2500\u2500 config.php\r\n\u251c\u2500\u2500 index.php\r\n\u251c\u2500\u2500 Pagination.class.php\r\n\u2514\u2500\u2500 css\/<\/span>\r\n \u2514\u2500\u2500 style.css\r\n<\/pre>\nPagination Library (Pagination.class.php)<\/h2>\n
Create a file named Pagination.class.php<\/code> to define the Pagination class that handles the pagination logic and link generation. <\/p>\n\n- This pagination library is a PHP class file that contains all the functions to create pagination links. You can include this file in your PHP script and create an object of the Pagination class to use the pagination functionality.<\/li>\n<\/ul>\n
The Pagination class accepts an array of parameters to customize the pagination links. Below are the list of parameters that you can use to customize the pagination links:<\/p>\n
\n$baseURL<\/code> – URL of the webpage.<\/li>\n$totalRows<\/code> – Total number of records.<\/li>\n$perPage<\/code> – Number of records to show per page.<\/li>\n$numLinks<\/code> – Number of links to show before and after the current page link.<\/li>\n$firstLink<\/code> – First link label.<\/li>\n$nextLink<\/code> – Next link label.<\/li>\n$prevLink<\/code> – Previous link label.<\/li>\n$lastLink<\/code> – Last link label.<\/li>\n$fullTagOpen<\/code> – Full open tag.<\/li>\n$fullTagClose<\/code> – Full close tag.<\/li>\n$firstTagOpen<\/code> – First open tag.<\/li>\n$firstTagClose<\/code> – First close tag.<\/li>\n$lastTagOpen<\/code> – Last open tag.<\/li>\n$lastTagClose<\/code> – Last close tag.<\/li>\n$curTagOpen<\/code> – Current open tag.<\/li>\n$curTagClose<\/code> – Current close tag.<\/li>\n$nextTagOpen<\/code> – Next open tag.<\/li>\n$nextTagClose<\/code> – Next close tag.<\/li>\n$prevTagOpen<\/code> – Previous open tag.<\/li>\n$prevTagClose<\/code> – Previous close tag.<\/li>\n$numTagOpen<\/code> – Number open tag.<\/li>\n$numTagClose<\/code> – Number close tag.<\/li>\n$showCount<\/code> – Show total records count.<\/li>\n$queryStringSegment<\/code> – Query string segment to get the current page number.<\/li>\n<\/ul>\nYou can customize the pagination links by changing the default values of the above parameters. Below is the complete code of the Pagination.class.php<\/code> file.<\/p>\n<?php
