Detecting if the cookies are enabled with PHP

For my current project I need a detection if the cookies are enabled or not in the user’s browser.
The easiest way to do this is by using this code:
<?php
setcookie('test', 1
, time()+3600
);
if(!isset($_GET['cookies'])){
header('Location:/info.php?cookies=true');
}
if(count($_COOKIE) > 0
){
echo "Cookies are yummy!";
} else {
echo "You didn't bring any cookies here. We are hungry!";
}
?> The CakePHP way is almost similar:
<?php
$this->Cookie->write('test', 1
);
if(!isset($_GET['cookies'])){
header('Location:/info.php?cookies=true');
}
if(count($_COOKIE) > 0
){
echo "Cookies are yummy!";
} else {
echo "You didn't bring any cookies here. We are hungry!";
}
?> Ok, it’s not rocket science, but it helps

Hm, are you sure this works? From the setcookie documentation: “Cookies will not become visible until the next loading of a page that the cookie should be visible for. To test if a cookie was successfully set, check for the cookie on a next loading page before the cookie expires.”
Daniel, you are absolutely right. That’s why I changed the code in the post.
My mistake is that I disabled/enabled the cookies without deleting them.
Probably I should leave this check to the JS, as it should be.
