How can data be securely transmitted to a remote server in PHP without exposing sensitive information?

To securely transmit data to a remote server in PHP without exposing sensitive information, you can use HTTPS protocol for secure communication. This ensures that the data is encrypted during transmission, making it difficult for unauthorized users to intercept and access sensitive information. 

// Set up cURL to make a secure HTTPS request to the remote server
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com/api');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)); // $data contains the sensitive information
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute the request and retrieve the response
$response = curl_exec($ch);

// Close cURL session
curl_close($ch);

// Process the response data
echo $response;
