I want to perform URL ENCRYPTION for my website......Can anyone help me.

whatever you do the url is readable, or it does not work
please define what you mean by encryption

if for a $_get, try $_post
try a session instead of sending url variables
send url variables as 1 2 3 and have the translation done serverside so the user does not know what they represent
if you just dont want the user to know the site filenames, mod_rewrite

none of those may apply, depending on what kind of url encryption you require

here is a long discussion with some code samples http://aspnet.4guysfromrolla.com/articles/083105-1.aspx
