What are common issues with implementing a pagination feature in PHP for displaying a limited number of entries per page?

Common issues with implementing a pagination feature in PHP include keeping track of the current page number, calculating the offset for fetching data from a database, and displaying the appropriate navigation links. To solve these issues, you can use a combination of GET parameters to track the current page, calculate the offset based on the page number and number of entries per page, and generate navigation links based on the total number of entries and the desired number of entries per page. 

<?php
// Assuming you have a database connection $conn

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

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

// Calculate offset
$offset = ($page - 1) * $limit;

// Fetch data from database
$stmt = $conn->prepare("SELECT * FROM entries LIMIT :limit OFFSET :offset");
$stmt->bindParam(':limit', $limit, PDO::PARAM_INT);
$stmt->bindParam(':offset', $offset, PDO::PARAM_INT);
$stmt->execute();
$entries = $stmt->fetchAll();

// Display entries
foreach ($entries as $entry) {
    echo $entry['title'] . "<br>";
}

// Generate navigation links
$total_entries = 100; // Total number of entries
$total_pages = ceil($total_entries / $limit);

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