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.

How to execute an UPDATE query in php
Aug 24, 2025 am 05:04 AM
Using MySQLi object-oriented method: establish a connection, preprocess UPDATE statements, bind parameters, execute and check the results, and finally close the resource. 2. Using MySQLi procedure method: connect to the database through functions, prepare statements, bind parameters, perform updates, and close the connection after processing errors. 3. Use PDO: Connect to the database through PDO, set exception mode, pre-process SQL, bind parameters, perform updates, use try-catch to handle exceptions, and finally release resources. Always use preprocessing statements to prevent SQL injection, verify user input, and close connections in time.
