Suggestions for designing a app

Thanks jameslittle.
I just tried base64_encode and it looks similar to some other implementations from places like Costco. That is probably the way they implemented it. It will definitely be interacting with a database and built in security is always a good idea. Thank You.

Before you get deep into base64__encode you should read The Comprehensive Guide to URL Parameter Encryption in PHP.

Thanks for sharing this Dave. If you can do it that way, the random token tied to the user record is definitely a more secure method than to pass variable data as an encoded string. The base64_encode path is more about obfuscation than actual encryption.
