I use crypt to encrypt the password of user and i need to send a password recovery email to the users when they ask for it. May i know how to decrypt the password stored in the database from encrypted form to the original string? Thank you.

The PHP crypt() function uses a one-way encryption algorithm. If you crypt the password with this function you could brute force it but I dought anyone would take that route for forgotten passwords.
Although you cannot un-encrypt the password you can easily generate them a new password and send them the new password via email, or you could even set up a temporary password they can login with. Once they login they can simply change there password.
Hope this helps!
