This question already has an answer here:
Could somebody tell me what's wrong? in the following code? I get the error Cannot modify header information - headers already sent.
<?php
class Cookie{
public static function exists($name){
return (isset($_COOKIE[$name])) ? true : false;
}
// Get the value of a cookie
public static function get($name){
return $_COOKIE[$name];
}
// Create a cookie
public static function put($name, $value, $expiry){
if(setcookie($name, $value, time() + $expiry, '/')){
return true;
}
return false;
}
// Delete Cookie
public static function delete($name){
self::put($name, '', time() -1);
}
}
?>
The error is from the above code I guess. I'm also including my Logout page since the error above is given when this code bellow is processed.
<?php
require_once ('functions/sanitize.php');
require_once('core/init.php');
include('includes/header.php');
$user = new User();
$user->logout();
?>
Bellow is the call stack
1 0.0002 237176 {main}( ) ../logout.php:0
2 0.0051 356400 User->logout( ) ../logout.php:7
3 0.0054 351736 Cookie::delete( ) ../User.php:125
4 0.0054 351864 Cookie::put( ) ../Cookie.php:24
5 0.0054 352008 setcookie ( ) ../Cookie.php:16
setCookie() thats where the error is
Anyways this is my header.php file which is included
