Are there any recommended resources or tutorials for understanding and implementing pagination functionality in PHP and MySQL databases?

Pagination functionality in PHP and MySQL databases allows for breaking large sets of data into smaller, more manageable chunks for display on a webpage. This is typically achieved by limiting the number of records fetched from the database at a time and providing navigation links to move between pages. 

<?php
// Establish a database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Define pagination variables
$limit = 10; // Number of records to display per page
$page = isset($_GET['page']) ? $_GET['page'] : 1; // Current page number
$offset = ($page - 1) * $limit; // Offset for fetching records

// Fetch records from the database with pagination
$sql = "SELECT * FROM table_name LIMIT $offset, $limit";
$result = $conn->query($sql);

// Display records on the webpage
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"] . " - Name: " . $row["name"] . "<br>";
    }
} else {
    echo "0 results";
}

// Generate pagination links
$sql_total = "SELECT COUNT(id) as total FROM table_name";
$result_total = $conn->query($sql_total);
$row_total = $result_total->fetch_assoc();
$total_pages = ceil($row_total["total"] / $limit);

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

// Close the database connection
$conn->close();
?>
