"Sqli-labs" Less21 cookie Injection-error based-complex-string (complex character-based cookie injection with error)

This is the same as LESS20, the only difference is that the parentheses are added and the cookie is encoded using the Base64 (because the Base64_decode decoding function is used)

The admin was encoded as ywrtaw4= but the SQL statements executed did not change

Add single quote encoding, and then modify the cookie

Then take the LESS20 code and make a code with base64.
