What are common issues when implementing a "Next Page" feature in PHP scripts?

One common issue when implementing a "Next Page" feature in PHP scripts is not properly handling the pagination logic, leading to incorrect results being displayed. To solve this, make sure to calculate the correct offset for fetching the next set of data based on the current page number and the number of items per page. 

// Get current page number
$page = isset($_GET['page']) ? $_GET['page'] : 1;

// Set number of items per page
$itemsPerPage = 10;

// Calculate offset for fetching data
$offset = ($page - 1) * $itemsPerPage;

// Fetch data using the calculated offset
$query = "SELECT * FROM table_name LIMIT $offset, $itemsPerPage";
$result = mysqli_query($connection, $query);

// Display data on the page
while($row = mysqli_fetch_assoc($result)) {
    // Display data here
}
