Are there any best practices for integrating traffic monitoring features using PHP on a website?

One best practice for integrating traffic monitoring features using PHP on a website is to use Google Analytics. This allows you to track various metrics such as page views, user demographics, and more. To integrate Google Analytics into your website, you can use the Google Analytics PHP API to send data from your website to Google Analytics.

// Include the Google API client library
require_once 'Google/autoload.php';

// Set up the Google client
$client = new Google_Client();
$client->setAuthConfig('client_secret.json');
$client->addScope(Google_Service_Analytics::ANALYTICS_READONLY);
$client->setAccessType('offline');

// Create an analytics service object
$analytics = new Google_Service_Analytics($client);

// Get the profile ID for the website
$profile = $analytics->management_profiles->listManagementProfiles('123456789', 'UA-12345678-1');
$profileId = $profile->getItems()[0]->getId();

// Send a pageview hit to Google Analytics
$analytics->data_ga->get(
    'ga:' . $profileId,
    '30daysAgo',
    'today',
    'ga:pageviews'
);
