Is it necessary to change something in a .ini file to make cookies globally visible on a hosted server?

To make cookies globally visible on a hosted server, you typically need to set the cookie domain to the root domain of your website in the php.ini file. This allows the cookies to be accessible across subdomains and directories within the same domain. You can achieve this by adding or modifying the "session.cookie_domain" directive in the php.ini file.

// Add or modify the following line in your php.ini file
session.cookie_domain = ".yourdomain.com"
