PHP to delete cookie in php class - php

Question

I am about to control my pages content. so that I need add or delete sessions/cookies. I maked a class that is working fine but in the cookie issue, it is not working as well. I checked with firefox 18 in windows7, and ubuntu 12.04 LTS. the cookies are not deleted using
setcookie(name, '', time()-9600)
foreach($this->_ck as $cookie)
{
$hrs=0;
if($plus)
{
$hrs=3600*$cfg_cookie_time;
}
//setcookie('testcookie13', '', time()-3600*6);
header("Set-Cookie: ".$cookie."=deleted; expires=Sun, 01-Jul-2012 08:59:12 GMT;");
}
etc...
My class is:
<?php
class headers{
var $new;
var $vars;
var $ss;
var $ck;
var $_ss;
var $_ck;
var $error;
var $catchs;
function _construct()
{
$this->new=false;
$this->error=false;
$this->ss=array();
$this->ck=array();
$this->_ss=array();
$this->_ck=array();
$this->catchs=true;
return $this->catchs;
} //f
function headers($hs = array(
"set" => array(
"ss" => array(),
"ck" => array()
)
))
{
if(isset($hs['send']))
{
$this->new=$hs['send'];
$this->catchs=true;
}
if(is_array($hs['set']))
{
if(is_array($hs['set']['ss']))
{
$this->ss = $hs['set']['ss'];
}
if(is_array($hs['set']['ck']))
{
$this->ck = $hs['set']['ck'];
}
}
if(is_array($hs['unset']))
{
if($hs['unset']['ss'])
{
$this->_ss = $hs['unset']['ss'];
}
if(is_array($hs['unset']['ck']))
{
$this->_ck = $hs['unset']['ck'];
}
}
return $this->catchs;
} //f
function send(
$cfg_cookie_time=6,
$plus=true
)
{
$cookie='';
if(is_array($this->ss))
{
session_start();
foreach($this->ss as $session){
$_SESSION['session'] = $session;
}
}
if($this->_ck)
{
foreach ($_COOKIE as $name => $value) {
setcookie($name, '', 1);
}
}
if($this->ck)
{
foreach($this->ck as $cookie => $val)
{
//$this->ck=$cookie.$val;
$hrs=0;
if($plus)
{
$hrs=3600*$cfg_cookie_time;
}
header("Set-Cookie: ".$cookie."=".$val."; path=/; domain=".$_SERVER['HTTP_HOST']."; expires=".gmstrftime("%A, %d-%b-%Y %H:%M:%S GMT;", time()+$hrs));
}
}
if($this->new)
{
header("location: ".$this->new);
$this->catchs=false;
}
header("X-Powered-By: PHP ".phpversion()."/FxPHP");
//header("HTTP/1.0 404 Not Found");
return $this->ck;
} //f
} // class
setcookie('H', '', -3600);
/*$hr = new HEADERS( array
(
"set" => array
(
"ck"=> array(),
"ss"=> array()
),
"unset" => array
(
"ck"=> array
(
"H" => "H"
),
"ss"=> array()
)
)
);
print_r( $_COOKIE).print_r($hr->send());
/*
" f" => "" ,
" sf" => "",
"my"=> "" ,
print_r(getallheaders());
print_r(setcookie('sd', 'dsds', 3600*6));
*/
?>
Can you any help?

Try it:
<?php
function del_cookie($_cookie = array())
{
foreach($_cookie as $k => $kv)
{
setcookie($k, '', time()-3600);
}
return;
}
function add_cookie($_cookie)
{
foreach($_cookie as $k => $kv)
{
setcookie($k, $kv, time()+3600*24*6);
}
return;
}
class headers{
var $new;
var $vars;
var $ss;
var $ck;
var $_ss;
var $_ck;
var $_ak;
var $_dk;
var $error;
var $catchs;
function _constract()
{
$this->new=false;
$this->error=false;
$this->ss=array();
$this->ck=array();
$this->_ss=array();
$this->_ck=array();
$this->catchs=true;
$this->_ak = false;
$this->_dk = false;
return $this->catchs;
} //f
function headers($hs = array(
"set" => array(
"ss" => array(),
"ck" => array()
)
))
{
if(isset($hs['send']))
{
$this->new=$hs['send'];
$this->catchs=true;
}
if($hs['set']['ck']['true'])
{
$this->ck = $hs['set']['ck'];
$this->_ak = true;
}
/*if($hs['unset']['ss'])
{
$this->_ss = $hs['unset']['ss'];
}
*/
if($hs['unset']['ck']['true'])
{
$this->_ck = $hs['unset']['ck'];
$this->_dk = true;
}
return $this->catchs;
} //f
function send(
$cfg_cookie_time=6,
$plus=true
)
{
if(is_array($this->ss))
{
session_start();
foreach($this->ss as $session){
$_SESSION['session'] = $session;
}
}
if($this->_dk)
{
del_cookie($this->_ck);
}
if($this->_ak)
{
add_cookie($this->ck);
}
if($this->new)
{
header("location: ".$this->new);
$this->catchs=false;
}
header("X-Powered-By: PHP ".phpversion()."/FxPHP");
//header("HTTP/1.0 404 Not Found");
return $this->catchs;
} //f
} // class
$hr = new HEADERS( array

(

(

(

)
)
);
print_r( $_COOKIE).print_r($hr->send());
/*
" f" => "" ,
" sf" => "",
"my"=> "" ,
print_r(getallheaders());
print_r(setcookie('sd', 'dsds', 3600*6));
*/
?>

Answer 2

One error I see in your code is
function _constract()
which should be
function __construct()

Answer 3

setcookie($cookie_name, null, null);
Will delete a cookie no matter what. Use that in plain php in the beginning of a script before any logic to verify that. If you're using this and your cookies are not being deleted you're either using xml requests or you have some issues in your logic. Good luck!
