[php] encryption

Hello folks.

I need your advice. I want to reversable encryp a string with a key. Which encryption method, supported by php, should I use?

Thanks.

you can use RC4, there's even a small function written by some guy... http://www.zend.com/codex.php?id=821&single=1

I'm sorry. I meant encoding, not encryption...
Does anyone know what I could use best to store a string of 10 alphanumeric characters (also signs like . and , ). Performance is not really an issue because encoding and decoding doesn't happen often.

Thanks.

I also heard about 3des and rijndael. What are advantages etc. What should be the best?

Thanks.
