Before we begin, make sure you have the following in place:
- A web server with PHP support.
Step 1: Create an HTML File
Let’s start by creating an HTML file where we’ll place the link that users will click to trigger the data capture.
In this code, we’ve created a simple HTML page with a link having the ID
captureLink. Clicking this link will initiate the data capture process.
Step 3: Create the PHP Script
<?php // Capture information received from the client $data = json_decode(file_get_contents('php://input'), true); // Store the captured information in a database or log it to a file // For this example, we will just append it to a log file $logFile = 'capture.log'; file_put_contents($logFile, json_encode($data) . PHP_EOL, FILE_APPEND); // Respond with a success message http_response_code(200); ?>
Step 4: Testing

In this tutorial, you’ve learned how to capture client-side data when someone opens a link on your website. This data can be valuable for analytics and tracking user behavior. Keep in mind that capturing some information, such as the client’s real IP address, may require additional server-side configurations due to security measures. Additionally, gathering GPU and device information might involve third-party libraries or APIs.
