setcookie for all subdomains

[johnsmith153]

I know PHP setcookie can set for all subdomains - by setting parameter 5 to something like ".domain.com".

 

However, I have quite a lot of code that just leaves param 5 blank (so sets for the current subdomain of that server).

 

Hopefully there'd be an easy way how to do this (a server setting?).

 

I know you can use ini_set('session.cookie_domain','http://domain.com'); but that only seems to set the session cookie value, not ones set in PHP.

 

I only really want it to ensure if someone accesses the site through both www.domain.com and domain.com that they use the same cookies.

Because it is the setcookie() statement that sends the cookie with whatever parameters are used in the function call and there are no default settings, you would need to modify the setcookie() statements.
