What are some common challenges when paginating content in PHP websites?

One common challenge when paginating content in PHP websites is correctly calculating the total number of pages based on the total number of items to display. This can be solved by dividing the total number of items by the number of items to display per page and rounding up to the nearest whole number. Another challenge is correctly fetching and displaying the appropriate subset of items for each page. This can be solved by using SQL queries with LIMIT and OFFSET clauses to fetch the correct subset of items for each page. 

// Calculate total number of pages
$totalItems = 100; // Total number of items
$itemsPerPage = 10; // Number of items to display per page
$totalPages = ceil($totalItems / $itemsPerPage);

// Fetch and display subset of items for current page
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$offset = ($page - 1) * $itemsPerPage;
$sql = "SELECT * FROM items LIMIT $itemsPerPage OFFSET $offset";
// Execute SQL query and display items
