Pagination in MySQL allows you to retrieve a specific subset of records from a larger dataset, which is essential for displaying data in manageable chunks. This is especially useful for applications that deal with large amounts of data, such as e-commerce sites or blogs.
To implement pagination, you typically use the `LIMIT` and `OFFSET` clauses in your SQL queries.
<?php
# Database connection
$connection = new mysqli('localhost', 'username', 'password', 'database');
# Define how many results you want per page
$results_per_page = 10;
# Find out the number of results in the database
$result = $connection->query("SELECT COUNT(*) AS total FROM your_table");
$row = $result->fetch_assoc();
$total_results = $row['total'];
# Determine number of pages
$number_of_pages = ceil($total_results / $results_per_page);
# Determine which page number visitor is on
$page = isset(<?php echo $_GET['page']; ?>) ? <?php echo $_GET['page']; ?> : 1;
# Determine the starting limit for the results on the displaying page
$starting_limit = ($page - 1) * $results_per_page;
# Retrieve the selected results from the database
$result = $connection->query("SELECT * FROM your_table LIMIT " . $starting_limit . ", " . $results_per_page);
while ($row = $result->fetch_assoc()) {
echo $row['column_name'] . "<br>";
}
# Display links for all pages
for ($page = 1; $page <= $number_of_pages; $page++) {
echo '<a href="pagination.php?page=' . $page . '">' . $page . '</a> ';
}
?>
