Does the server traffic for external data retrieval in PHP get attributed to the user accessing the website?

When a user accesses a website that retrieves external data in PHP, the server traffic for fetching that data is typically attributed to the server where the PHP code is running, not the user accessing the website. To solve this issue and properly attribute the server traffic to the user, you can implement a caching mechanism that stores the retrieved external data locally on the server and serves it to subsequent users without needing to fetch it again. 

// Check if the cached data exists
$cached_data = get_cached_data();

if (!$cached_data) {
    // Fetch external data and save it to cache
    $external_data = fetch_external_data();
    save_to_cache($external_data);
    
    // Use the fetched data
    echo $external_data;
} else {
    // Use the cached data
    echo $cached_data;
}

function get_cached_data() {
    // Implement logic to retrieve cached data from the server
}

function fetch_external_data() {
    // Implement logic to fetch external data
}

function save_to_cache($data) {
    // Implement logic to save data to cache on the server
}
