You can do this by using session_start() On the start of your home page add this line

session_start() now on you login page do the following

if(isset($_SESSION['user'])){
     // redirect user to $_SERVER['HTTP_REFERER']
 }

and in your login function after successful login do this

$_SESSION['user'] = //<user name of logged in user>

on logout do this

session_destroy()

$_SESSION array can hold any number of user defined values, you can use this to store all the data related to a session

$_SERVER['HTTP_REFERER'] will take user to the last url, you might want to change it according to your requirements
