I created a userpanel which is accessible when a user registers and log's in. Everything works fine but when I want to exit the userpanel these errors occure:
Notice: A session had already been started - ignoring session_start() in C:\xampp\htdocs\eshop\userpanel_exit.php on line 2
Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\eshop\top.php:230) in C:\xampp\htdocs\eshop\userpanel_exit.php on line 4
Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\eshop\top.php:230) in C:\xampp\htdocs\eshop\userpanel_exit.php on line 5
my exit section code:
**
<?php
session_start();
unset($_SESSION['email']);
setcookie('remember','',time()-3600,'/');
header('location:login.php');
?>
**
my userpanel code:
<?php
session_start();
if(!isset($_SESSION['email'])){
if(isset($_COOKIE['remember'])){ $_SESSION['email']=$_COOKIE['remember']; }
else{ header('location:login.php'); }
}
include('connect.php');
$query="select * from tblusers where email='".$_SESSION['email']."' ";
$stmt=$db->prepare($query);
$stmt->execute();
$myresult=$stmt->fetch(PDO::FETCH_ASSOC);
