What best practices can be implemented to improve the performance of PHP scripts handling large amounts of data for PDF generation?

When handling large amounts of data for PDF generation in PHP scripts, it is important to optimize the code for performance. One way to improve performance is to use pagination to limit the amount of data processed at once. This can help reduce memory usage and processing time. 

// Example code snippet for implementing pagination in PHP for PDF generation

// Set the limit of records to fetch per page
$limit = 100;

// Calculate the offset based on the current page number
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$offset = ($page - 1) * $limit;

// Query to fetch data with pagination
$query = "SELECT * FROM data_table LIMIT $offset, $limit";
$result = mysqli_query($connection, $query);

// Loop through the fetched data and generate PDF
while ($row = mysqli_fetch_assoc($result)) {
    // Generate PDF content for each row
}

// Add pagination links for navigating between pages
// Example: echo "<a href='?page=1'>First</a> | <a href='?page=2'>Next</a> | <a href='?page=3'>Last</a>";
