Hello,

how can i set a cookie on different subdomains ?

I would do something like this:


setcookie("key", "value1", 0, "/", "subdomain1.server.com");
setcookie("key", "value2", 0, "/", "subdomain2.server.com");


change the expire time name and value of the cookies accordingly.

To set separate cookie for separate subdomains use Kohrar's code. If you want same cookie accessible from multiple subdomains use
setcookie('key', 'value', 0, '/', '.domain.com');

I have about 7 subdomains, well i'm going to try

setcookie('key', 'value', 0, '/', '.domain.com');
