PHP Setcookie problem

[Bingo]

Hi,

I have a problem with setcookie in PHP.
I'm running XAMPP on Win XP SP2.

I have a PHP script which looks for a cookie and if not found, tries to set one and refresh the page. The script however enters an infinite loop as it cannot set the cookie.

Here's my code (cookie.php):

// CREATE COOKIE
if (empty($sessionid)) {
 header("Refresh: 0;url=cookie.php");
 setcookie ("sessionid", md5 (uniqid (rand())),
 time()+7200);
 exit();
}

Appreciate any suggestions as to why this is happening!?

Thanks,
Bingo

Hi Bingo,

I`m guessing the problem is because you are calling the header function before the cookie is set, so it would keep looping. Try:

if (empty($_COOKIE['sessionid'])) {
setcookie ("sessionid", md5 (uniqid (rand())),
time()+7200);
header("Refresh: 0;url=cookie.php");
exit();
}

Also, note the use of the superglobal $_COOKIE. Thats just in case you have register globals OFF.

Thanks dreamcatcher, but just realised I pasted the code wrong! It is in fact:

// CREATE COOKIE
if (empty($sessionid)) {
 setcookie ("sessionid", md5 (uniqid (rand())), time()+7200);
 echo header("Refresh: 0;url=cookie.php");
 exit();
}

Pretty sure it's server config.
Anyone out there using XAMPP (Apache 2.0) on local?

Thanks,
Bingo

You have an error with your header. Refer to the HTTP/1.1 specification [faqs.org] for more details on this. Also, add

error_reporting(E_ALL);

to the top of the script to find any more errors that you may have.
