What are the potential pitfalls of displaying monthly data with pagination in PHP?

When displaying monthly data with pagination in PHP, a potential pitfall is that the pagination logic may not accurately reflect the total number of records for that specific month, leading to incorrect page navigation. To solve this issue, you should ensure that the pagination logic takes into account the total number of records for the selected month before displaying the pagination links. 

// Calculate total number of records for the selected month
$totalRecords = // Query to get total number of records for the selected month

// Set the number of records to display per page
$recordsPerPage = 10;

// Calculate total number of pages
$totalPages = ceil($totalRecords / $recordsPerPage);

// Get the current page number
if (isset($_GET['page']) && is_numeric($_GET['page'])) {
    $currentPage = $_GET['page'];
} else {
    $currentPage = 1;
}

// Display pagination links
for ($i = 1; $i <= $totalPages; $i++) {
    echo "<a href='monthly_data.php?month=12&page=$i'>$i</a> ";
}
