Encrypting - Decrypt same variable - PHP

Question

If my variable looks like this:

$name = "John";

and I want the above variable, to be encrypted to something like:

 encrypt($name) //Will output something like: AIfzx353HA7f (Just random chars)

And then, be able to decrypt it, so it will output John again.

decrypt($name) //Will output John

Is this possible to do with PHP?

You can use different types of algorithms to do this. Maybe you can take a look at Mcrypt here. (in particular mcrypt_encrypt and mcrypt_decrypt)
