check the person who accessed the admin page must be filled the input fields like email and password before accessing the admin page
there must be a logout button for exiting account
login.php:
<?php
if(isset($_POST['save']))
{
echo"hello";
session_start();
$_SESSION['email']=$_POST['useremail'];
$_SESSION['pass']=$_POST['userpass'];
header('Location:admin.php');
}
?>
<html>
<head>
</head>
<body>
<form method="post">
<div>
<div><label>email</label></div>
<input type="email" name="useremail" required>
</div>
<div>
<div><label>password</label></div>
<input type="password" name="userpass" required>

admin.php
after login, admin.php is a file that is accessed after login.<?php
session_start();
if(isset($_SESSION['email'] ) && isset($_SESSION['pass'] ))
{
echo $_SESSION['email'];
echo $_SESSION['pass'];
}
else
{
session_unset();
session_destroy();
header('Location:login.php');
}
#unset the session value: session_unset();
#end the session:sessionn_destroy();
#move to the login page after logout:header('Location:login.php');
