How can PHP developers optimize their code to reduce server load when creating offline readers?

PHP developers can optimize their code to reduce server load when creating offline readers by implementing caching mechanisms to store previously fetched data locally and only making requests to the server when necessary. This can help reduce the number of requests made to the server and improve the overall performance of the offline reader. 

// Check if data is already cached locally
if (file_exists('cached_data.json')) {
    $data = file_get_contents('cached_data.json');
} else {
    // Make request to server and fetch data
    $data = fetchDataFromServer();
    
    // Cache data locally
    file_put_contents('cached_data.json', $data);
}

// Process and display the fetched data
echo $data;
