PHP で単純なページネーションを実装するにはどうすればよいですか?

// 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>
