How to set and check for a cookie?

I don't really want to indulge in something else I know nothing about, and also like I said, the host confirmed that php, sessions and cookies were working fine. It must be something else in my code that I'm doing wrong

 

I've tried taking the most basic cookie function from w3 schools andplacing it in random places, and even where setcookie is in the html head section

nada

<?php
$expire=time()+60*60*24*30;
setcookie("user", "Alex Porter", $expire);
?>

<?php
// Print a cookie
echo $_COOKIE["user"];

// A way to view all cookies
print_r($_COOKIE);
?>

print_r returns a whole mess of crap like before

 

Tested on another domain, still the same

however they were the same host

 

try using another web browser, maybe your browser settings does not allow cookies it may be! If this wont resolve then its for sure your web server configurations.
