How can PHP be optimized to efficiently handle large datasets and improve navigation functionality on a webpage?

To optimize PHP for handling large datasets and improve navigation functionality on a webpage, you can utilize techniques such as pagination to limit the number of records fetched at once, caching frequently accessed data, and optimizing database queries. Additionally, you can use efficient data structures and algorithms to process and display data quickly. 

// Example pagination code to limit the number of records fetched at once
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$records_per_page = 10;
$offset = ($page - 1) * $records_per_page;

$query = "SELECT * FROM large_table LIMIT $offset, $records_per_page";
// Execute the query and display the results
