What are some recommended resources or tutorials for implementing pagination in PHP?

When displaying a large amount of data on a web page, it is important to implement pagination to break up the content into manageable chunks. Pagination allows users to navigate through the data easily without overwhelming them with too much information at once. One common way to implement pagination in PHP is by using SQL queries to limit the number of results displayed on each page. 

<?php

// Connect to database
$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 variables for pagination
$results_per_page = 10;
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$start_from = ($page - 1) * $results_per_page;

// Fetch data from database with pagination
$sql = "SELECT * FROM table LIMIT $start_from, $results_per_page";
$result = $conn->query($sql);

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

// Pagination links
$sql = "SELECT COUNT(id) AS total FROM table";
$result = $conn->query($sql);
$row = $result->fetch_assoc();
$total_pages = ceil($row["total"] / $results_per_page);

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

$conn->close();

?>
