How can PHP developers ensure that commands are sent securely and without exposing sensitive information during domain communication?

To ensure that commands are sent securely and without exposing sensitive information during domain communication, PHP developers can use HTTPS protocol for secure communication and encryption techniques such as SSL/TLS. Additionally, developers should avoid passing sensitive information in URLs and instead use POST requests with encrypted data. 

// Example code snippet using HTTPS for secure communication
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com/api');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// Example code snippet using POST request with encrypted data
$data = array('username' => 'user123', 'password' => 'securePassword');
$encryptedData = encryptData($data);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com/api');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $encryptedData);
$response = curl_exec($ch);
curl_close($ch);
