What are common challenges faced when implementing a pagination function in PHP for displaying news articles?

One common challenge when implementing pagination for news articles in PHP is correctly calculating the offset for fetching the correct subset of articles. This can be solved by using the LIMIT and OFFSET clauses in the SQL query to retrieve only the desired range of articles.

// Assuming $page is the current page number and $limit is the number of articles per page
$offset = ($page - 1) * $limit;
$query = "SELECT * FROM news_articles LIMIT $limit OFFSET $offset";
// Execute the query and display the articles
