You need to save an ID, something you can use to identify users by, to a
cookie. Something like...

$setcookie( 'userId', $userID );

Then when they come back check for the value in the cookie structure.

if (isset( $_COOKIE['userId'] ))
{
$userId = $_COOKIE['userId'];
}

But, you have to be careful with the security risk this creates. At least
make sure that $userId is not a sequential number so it can't be faked to
gain unathorized access to someone else's records.

I user sessions..
Does that have anything to do with this..?
I mean, I can still use sessions and for the "Remember me" option I
will use cookies..Right..?
I also heard I need to make the cookie expire after a long will..
I tried doing it but didn't know how it works.. :S

You use the session to track a user's actions through your site. By default
a session lasts as long as the browser is open, but this can be changed.

You use the cookie to identify a user. But when they return the next time
they will probably start a new session.

Here's how to set the expiration of your cookie:
