PHP url encryption and decryption Function Code

Copy codeThe Code is as follows:
$ ReturnUrl = rawurlencode (base64_encode ($ returnUrl); // Encoding

$ ReturnUrl = parse_str (base64_decode ($ returnUrl); // decodes or
$ ReturnUrl = base64_decode ($ returnUrl); // decode

// Or

// I don't know why. The first decoding method above returns null and solves the problem.
$ ReturnUrl = base64_encode ($ returnUrl); // Encoding
$ ReturnUrl = base64_decode ($ returnUrl); // decode

This is a method, but it is the safest, because it can be solved as long as you know the principle, but you do not have high requirements.

If you want to be safe, you need to use a dedicated encryption class.
