What is the significance of knowing the origin of a visitor to a website in PHP?

Knowing the origin of a visitor to a website in PHP can be significant for tracking marketing campaigns, understanding user behavior, and personalizing the user experience. By capturing and analyzing the referrer information, website owners can determine which sources are driving traffic to their site and optimize their marketing strategies accordingly. 

// Get the referrer URL of the visitor
$referrer = isset($_SERVER['HTTP_REFERER']) ? $_SERVER['HTTP_REFERER'] : 'Direct';

// Store the referrer information in a session variable for further analysis
session_start();
$_SESSION['referrer'] = $referrer;
