How can PHP developers effectively troubleshoot and debug pagination issues in their code?

To effectively troubleshoot and debug pagination issues in PHP code, developers can start by checking the pagination logic, ensuring that the correct number of items are being displayed per page and that the pagination links are generated accurately. They can also verify that the total number of items and the current page number are being calculated correctly. Additionally, developers can use debugging tools like var_dump() or print_r() to inspect variables and identify any errors in the pagination process. 

// Example pagination logic
$items_per_page = 10;
$current_page = isset($_GET['page']) ? $_GET['page'] : 1;
$total_items = count($items); // Assuming $items is an array of items to paginate

$start_index = ($current_page - 1) * $items_per_page;
$paginated_items = array_slice($items, $start_index, $items_per_page);

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

// Display paginated items
foreach ($paginated_items as $item) {
    echo $item . '<br>';
}
