How can the concept of pagination be effectively implemented in PHP to display a limited number of entries per page and provide navigation to view additional entries in a database?

To implement pagination in PHP, you can use the LIMIT clause in SQL queries to fetch a specific number of entries per page. Additionally, you can calculate the total number of pages based on the total number of entries and the desired entries per page. Finally, you can create navigation links to allow users to move between pages. 

<?php
// Assuming $conn is your database connection

// Number of entries per page
$entriesPerPage = 10;

// Current page number
$page = isset($_GET['page']) ? $_GET['page'] : 1;

// Calculate the starting entry for the current page
$start = ($page - 1) * $entriesPerPage;

// Query to fetch entries for the current page
$sql = "SELECT * FROM entries LIMIT $start, $entriesPerPage";
$result = mysqli_query($conn, $sql);

// Display entries
while($row = mysqli_fetch_assoc($result)) {
    // Display entry data
}

// Calculate total number of entries
$totalEntries = mysqli_num_rows(mysqli_query($conn, "SELECT * FROM entries"));

// Calculate total number of pages
$totalPages = ceil($totalEntries / $entriesPerPage);

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