>Solution :
Encrypted data is generally binary data, and the characters you show in your question suggest that’s the case in your application.
A good solution to your problem is to use base64_encode() to convert your encrypted binary data to text before putting it into MySQL, and base64_decode() to get back the binary data after you read it from MySQL.
Warning: RC4 encryption is not secure. It’s been cracked for almost a decade. If you use it to store sensitive credit card data, it is very likely that cybercriminals will steal that data. Your customers won’t like that.
If you want to handle credit card data, your best bet is to use a payment service provider like stripe.com, paypal, or one of many others. You don’t want credit card numbers, even encrypted ones, stored in your database.
