Keep logged in on each page

When i log in on my index.php, and then go to another page like members.php, i am a guest again. How can i do so they are logged in on each site? I know that sessions are involved, but cant figure it out. Any help is needed!

EDIT: Ok, so i have tried some stuff that you guys have commented and this is my final code:

my index.php

<?php
session_start();
?>

First you need to set a session on login with the following code:

session_start();

Then with $_SESSION you can check if the user got a session and is logged in. 

If(isset($_SESSION)){
    //loged in code 
} else{
    //other code 
}

assing a session variable:

$_SESSION['mySessionName'] = "yourvalue";

than you could check if it is set with 

if(isset($_SESSION['mySessionName']))

(from Richard in comments)

For more information about sessions go to http://php.net/manual/en/book.session.php

hope this helped

You would want to use PHP Sessions.
Once you log in, you start a session.
There is a super global $_SESSION. You could save your session data to this.
This is persistent and will stay intact until you unregister your variables or end your session.

One common mistake a beginner would do is forget the session_start() method.
To use session super global, you must call the session_start() function.

From my understanding, you seem to be a beginner with sessions. You would want to check PHP Sessions on w3schools.com. But make sure you move on to something else as soon as you get some basic understanding about what sessions are.

Hope this helps!
