encrypting data in PHP and then display it unencrypted back to the browser

I want to store some information in mySQL and want to encrypt it so that it
isnt easily read by anyone else. But then I want to be able to deencrypt it
when it is displayed in a browser over a secure link. Any ideas how to
achive this as most encryption that we have looked at is like md5 which is
one way.

What is the point in encrypting data if it can be decrypted ?

The idea is that it would be decrypted on a VPN. Data would be collected
over the internet using SSL and stored. Over a secure link we would retrive
that data, the decryption would only happen from one IP address.
