How can I use PHP to improve the tracking and analysis of visitor sources on my website?

To improve tracking and analysis of visitor sources on your website using PHP, you can utilize cookies or session variables to store the referral source when a visitor first lands on your site. This information can then be passed along in subsequent page views or form submissions for analysis. 

// Set referral source in a cookie when a visitor first lands on the site
if(!isset($_COOKIE['referral_source'])) {
    $referral_source = isset($_SERVER['HTTP_REFERER']) ? $_SERVER['HTTP_REFERER'] : 'Direct Traffic';
    setcookie('referral_source', $referral_source, time() + 3600, '/');
}

// Retrieve referral source from cookie for tracking and analysis
$referral_source = isset($_COOKIE['referral_source']) ? $_COOKIE['referral_source'] : 'Direct Traffic';

// Use $referral_source variable for tracking and analysis purposes
