How can PHP be used to track and analyze user engagement with newsletter links?

To track and analyze user engagement with newsletter links using PHP, you can create unique tracking URLs for each link in the newsletter. These URLs can include parameters to identify the specific link and user. When a user clicks on a link, you can capture and store this data in a database for analysis.

// Assuming $newsletterLink contains the URL of the newsletter link
$trackingUrl = $newsletterLink . '?utm_source=newsletter&utm_medium=email&utm_campaign=engagement_tracking';

// Redirect the user to the tracking URL
header('Location: ' . $trackingUrl);

// Capture and store user engagement data in a database
// Insert code here to store data such as user ID, link clicked, timestamp, etc.
