I want to implement this code for bank payment in PHP. Can anyone help me? Thanks.

ASCIIEncoding ByteConverter = new ASCIIEncoding(); string dataString = "Data to Sign"; ‬ byte[] originalData = ByteConverter.GetBytes(dataString); byte[] signedData; RSACryptoServiceProvider RSAalg = new RSACryptoServiceProvider(); String PrivateKey= File.ReadAllText(Application.StartupPath + "PrivateKey.xml"); RSAalg.FromXmlString(PrivateKey); signedData = Key.SignData(originalData,SHA1.Create()); String base64String = Convert.ToBase64String(signedData, 0, signedData.Length); ‬

I've tried this but didn't get any results. Due to a problem with the request, I got a symbol error.

$baseString = "Data to Sign"; $signedData = null; $privateKey = file_get_contents(config_path("PrivateKey.pem")); $privateKeyResource = openssl_pkey_get_private($privateKey); $signature = null; if (openssl_sign($baseString, $signedData, $privateKeyResource, OPENSSL_ALGO_SHA1)) $signature = base64_encode($signedData);
