How to read cookie from subdomain in PHP?

Question

Can anyone tell me how to read cookie from subdomain. I can set the cookie for subdomain but unable to read it.

Please tell me what is the syntax in PHP to read cookie from subdomain.

Answer 1

If you're enabled to read in other subdomain, it's probably because you didn't properly set the cookie to begin with.

$date_of_expiry=time()+ 3600; setcookie( "cookie_name", "cookie_value", $date_of_expiry, "/", "example.com" );

It's important that you put the last argument for the cookie to be available in other subdomains.

Also, the cookies must be set before page output.
