How can PHP developers effectively manage and display large datasets while implementing pagination features?

To effectively manage and display large datasets while implementing pagination features in PHP, developers can use SQL queries with LIMIT and OFFSET clauses to fetch only a subset of data at a time. This allows for better performance and faster loading times when dealing with large datasets. Additionally, developers can use pagination links or buttons to navigate between different pages of data. 

// Example PHP code snippet for implementing pagination with MySQL database

// Establish database connection
$connection = mysqli_connect("localhost", "username", "password", "database");

// Define variables for pagination
$limit = 10;
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$offset = ($page - 1) * $limit;

// Fetch data from database with pagination
$query = "SELECT * FROM table_name LIMIT $limit OFFSET $offset";
$result = mysqli_query($connection, $query);

// Display data
while($row = mysqli_fetch_assoc($result)) {
    echo $row['column_name'] . "<br>";
}

// Create pagination links
$total_records = mysqli_num_rows(mysqli_query($connection, "SELECT * FROM table_name"));
$total_pages = ceil($total_records / $limit);

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