How can a PHP script on a server generate a request to a third-party server without revealing the variables to the browser?

When generating a request to a third-party server from a PHP script on a server without revealing the variables to the browser, you can use cURL to send the request. By using cURL, the request is made server-side without involving the browser, thus keeping the variables hidden from the client-side. 

<?php
// Set the variables to be sent in the request
$data = array(
    'variable1' => 'value1',
    'variable2' => 'value2'
);

// Initialize cURL session
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'http://third-party-server.com/api');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute the cURL session
$response = curl_exec($ch);

// Close cURL session
curl_close($ch);

// Process the response from the third-party server
echo $response;
?>
