what variable is the user's e-mail address?

[budduke]

I am working with the login.php in the root directory and I am trying to see how I retrieve the user's e-mail address as they are loggin in. No, not having them type it in, I mean pulling the e-mail from the database as they are logging in.
I am adding to the script so the user will also log into another part of my site at the same time but that side needs thier e-mail address also during its login.
I have tried
$test= $user_email;
$test= user_info['user_email'];

and a few others and they all respond with a empty field.

the commented  area is where I am trying to add my hack for the other part of my site...
