How can PHP developers improve performance when dealing with a high number of database records in their applications?

When dealing with a high number of database records in PHP applications, developers can improve performance by implementing pagination. This involves fetching and displaying a limited number of records per page, reducing the load on the database and improving the overall user experience. 

// Calculate pagination variables
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$records_per_page = 10;
$offset = ($page - 1) * $records_per_page;

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

// Display records
while ($row = mysqli_fetch_assoc($result)) {
    // Display record data
}
