you can done this with session. more detail about session : LINK

<?php
  if(isset($_SESSION['login'])) {  
    header ("Location:dashboard.php");
  }
  else
  {
    header ("Location: login.php");
  }
?>

in this check if session is set then a user is login then redirect it to dashboard.php or if session is not set then it redirect to login.php page.

in login page set the session $_SESSION['login'] with 1 or 0 value. or also you can store a username .


In a website a user login is most of the time defined as a PHP-session. The answer for your question is to check if the session exists on the pages that need a login. If the session doesn't exist the user gets redirected to the login page

Example:

if(!isset($_SESSION['login']))
{
   header('location: login.php');
}
else
{
   //Do nothing because the user is logged in.
}
