I want a function like md5() by which I can encrypt a code and

but in md5() this func. is not there. I can not go in reverse
way.
If a simple PHP function could encrypt and decrypt data with no
arguments other than the string, anyone could decrypt your data. In
other words, it can't be as simple as md5().
You might find the code samples at the bottom of this page helpful:
http://phpsecurity.org/code
They primarily cover using mcrypt. There's also an article by Robert
Peake that's pretty good:

Hope that helps.
