}
// use:
//$value = porosh_encrypt($data_input);/// For encrypt
//$value = porosh_decrypt($encoded_64);// For Decrypt
// just include those functions with your script
//$input_data is a variable which can be use for the data you need to encrypt.
//$encoded_64 is also a variable which will be used to store the data after
//it's encrypted and then encoded with the base64_encode() function.
