How can PHP developers optimize their code to improve performance when handling large amounts of data in a MySQL database?

When handling large amounts of data in a MySQL database, PHP developers can optimize their code by using proper indexing, limiting the number of queries, and utilizing caching techniques. One common technique is to use pagination to limit the number of records fetched at a time, reducing the load on the server and improving performance. 

// Example code snippet implementing pagination to optimize performance when handling large amounts of data in a MySQL database

// Set the number of records to fetch per page
$records_per_page = 10;

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

// Query to fetch records with pagination
$query = "SELECT * FROM table_name LIMIT $offset, $records_per_page";
$result = mysqli_query($connection, $query);

// Loop through the fetched records
while ($row = mysqli_fetch_assoc($result)) {
    // Process each record
}

// Display pagination links for navigating through pages
// This can be done using a separate function or library
