How can one ensure the security of access credentials when using SOAP for database interaction in PHP?

To ensure the security of access credentials when using SOAP for database interaction in PHP, it is recommended to encrypt the credentials before sending them over the network. This can be achieved by using a secure encryption algorithm and key management system. Additionally, implementing HTTPS for secure communication can further enhance the security of the access credentials. 

// Encrypt access credentials before sending over SOAP
$credentials = 'username:password';
$encryptedCredentials = openssl_encrypt($credentials, 'AES-256-CBC', 'encryption_key', 0, 'encryption_iv');

// Send encrypted credentials over SOAP
$client = new SoapClient("https://example.com/soap.wsdl", array('trace' => 1));
$response = $client->__soapCall("method", array($encryptedCredentials));

// Decrypt credentials on the server side
$decryptedCredentials = openssl_decrypt($response, 'AES-256-CBC', 'encryption_key', 0, 'encryption_iv');
list($username, $password) = explode(':', $decryptedCredentials);
