How to Implement Pagination in PHP
PHP offers an easy and effective solution for implementing pagination on a website. This technique can be used to display data in chunks, enhancing the user experience and optimizing database queries.
Let's explore a simplified script that demonstrates pagination in PHP:
// Define constants for pagination
const LIMIT = 20;
// Get the total number of records in the table
$total = $dbh->query('SELECT COUNT(*) FROM table')->fetchColumn();
// Calculate the number of pages based on the total and limit
$pages = ceil($total / LIMIT);
// Determine the current page number or set a default
$page = min($pages, filter_input(INPUT_GET, 'page', FILTER_VALIDATE_INT, [
'options' => [
'default' => 1,
'min_range' => 1,
],
]));
// Calculate the offset for the query
$offset = ($page - 1) * LIMIT;
// Display paging information
echo "<div>
This script provides a basic example of pagination, where you can adjust the LIMIT constant to specify the number of records to display per page. By calculating the total number of pages based on the total number of records, you can implement dynamic pagination.
Utilizing this simplified script or further customizing it according to your specific requirements, you can enhance the usability of your PHP applications by offering convenient pagination to your users.
