How can PHP scripts be optimized to handle large amounts of data efficiently?

To optimize PHP scripts to handle large amounts of data efficiently, consider using techniques such as pagination, caching, optimizing database queries, and using efficient data structures. Pagination helps limit the amount of data processed at once, caching reduces the need to repeatedly fetch data, optimizing queries ensures only necessary data is retrieved, and using efficient data structures can improve performance. 

// Example of implementing pagination in PHP
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$limit = 10;
$offset = ($page - 1) * $limit;

// Query database with pagination
$query = "SELECT * FROM table LIMIT $limit OFFSET $offset";
$result = mysqli_query($connection, $query);

// Process and display data
while ($row = mysqli_fetch_assoc($result)) {
    // Display data
}
