What are the common differences in behavior between local and hosted servers when dealing with PHP cookies?

Local servers often have different configurations than hosted servers, which can lead to differences in how PHP cookies are handled. One common issue is that the cookie domain may need to be adjusted when moving from a local server to a hosted server. To solve this, make sure to set the cookie domain parameter to the appropriate domain when setting the cookie in PHP.

// Set the cookie with the appropriate domain
setcookie("cookie_name", "cookie_value", time() + 3600, "/", "yourdomain.com");
