What are the best practices for handling non-sequential ID numbers in a MySQL database when implementing pagination in PHP?

When dealing with non-sequential ID numbers in a MySQL database for pagination in PHP, it is important to use the LIMIT and OFFSET clauses in your SQL query to retrieve the correct subset of data. You should also order the results by the ID column to ensure consistency. Additionally, you may need to adjust your pagination logic to handle non-sequential IDs properly. 

$page = isset($_GET['page']) ? $_GET['page'] : 1;
$limit = 10;
$offset = ($page - 1) * $limit;

$sql = "SELECT * FROM table_name ORDER BY id LIMIT $limit OFFSET $offset";
$result = mysqli_query($conn, $sql);

while ($row = mysqli_fetch_assoc($result)) {
    // Output data
}

// Pagination links
$total_pages = ceil($total_records / $limit);
for ($i = 1; $i <= $total_pages; $i++) {
    echo "<a href='?page=$i'>$i</a> ";
}
