Php Password recovery with secret question script

I am needing a password recover script.

This script must include a password recovery script.

I am needing for the person to reset there password, need to first answer a form named: Your Email.

If the email is found, it goes to another form that asks for the secret answer.


Then it goes to a form that asks the answer of there secret question that they entered when they first signed up.

If the answer is correct it updates the database table value of the password with a random string generated with:

abcdefghijklmnopqrstuvwxyz023456789

And it also, sends that password to the email provided.
