Need to get cookie domain

Hello,

I set my cookies using setcookie like this for exp:


setcookie("username", $_SESSION['username'], 2147483647, "/", ".$cookiedomain", 0);


where $cookiedomain is my domain name without www, like mydomain.com, mysite.net etc.

My question is, can I get this variable automatically from an environment or server variable? $_SERVER["HTTP_HOST"] gives something like www.mydomain.com and I could trim it but will it give correct value on every server? And, which one is more reliable, ENV or SERVER?

Thanks,

try this, this has worked for me plenty of times


$cookiedomain = $_SERVER["SERVER_NAME"];

setcookie("username", $_SESSION['username'], 2147483647, "/", ".$cookiedomain", 0);


good luck

Hi, thanks for the reply!

You determine the $cookiedomain as the value of $_SERVER['SERVER_NAME']. I guess this may work for you cause you always used the same server or a shared hosting? Maybe the SERVER_NAME can be different something than a domain name.

And, your cookie will be useful only on www domain. I want it to be useful for people without www domain too.

So, I wrote the following:



$cookiedomain = $_SERVER['HTTP_HOST'];
if(strtolower(substr($cookiedomain, 0, 4)) == 'www.') {
$cookiedomain = substr($cookiedomain, 4);
}
$cookiedomain = '.' . $cookiedomain;

setcookie("username", $_SESSION['username'], 2147483647, "/", $cookiedomain, 0);

it shouldn't do that, it takes the server name from the url so if they go http://mysite.com/ it will output mysite.com if it is http://www.mysite.com the output will be www.mysite.com
