What are some potential pitfalls of using the MySQL LIMIT function in PHP to limit the number of displayed news items?

One potential pitfall of using the MySQL LIMIT function in PHP to limit the number of displayed news items is that it only limits the number of rows returned from the database query, not the total number of news items displayed on the page. To solve this issue, you can use PHP to count the total number of news items and adjust the LIMIT clause accordingly. 

// Connect to database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Query to get total number of news items
$total_news_query = "SELECT COUNT(*) as total_news FROM news";
$total_news_result = mysqli_query($connection, $total_news_query);
$total_news = mysqli_fetch_assoc($total_news_result)['total_news'];

// Calculate offset and limit for pagination
$limit = 10; // Number of news items per page
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$offset = ($page - 1) * $limit;

// Query to get limited news items
$news_query = "SELECT * FROM news LIMIT $offset, $limit";
$news_result = mysqli_query($connection, $news_query);

// Display news items
while ($row = mysqli_fetch_assoc($news_result)) {
    echo $row['title'] . "<br>";
}

// Pagination links
$total_pages = ceil($total_news / $limit);
for ($i = 1; $i <= $total_pages; $i++) {
    echo "<a href='news.php?page=$i'>$i</a> ";
}
