How can PHP be used to create a pagination system for displaying a certain number of entries per page?

To create a pagination system in PHP for displaying a certain number of entries per page, you can use a combination of SQL queries to fetch the data and calculate the total number of pages needed. Then, you can use URL parameters to navigate between different pages of the data set. 

<?php
// Define the number of entries per page
$entries_per_page = 10;

// Calculate the total number of pages based on the total number of entries
$total_entries = // query to get total number of entries
$total_pages = ceil($total_entries / $entries_per_page);

// Get the current page number from the URL parameter
$current_page = isset($_GET['page']) ? $_GET['page'] : 1;

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

// Query to fetch entries for the current page
$query = "SELECT * FROM entries LIMIT $start, $entries_per_page";
$result = // execute the query

// Display the entries
while ($row = // fetch entries from $result) {
    // display entries
}

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