PHP setcookie () usage
 

Parameters	Description	Example
Name	Name of the required Cookie	Use $ _ COOKIE ['cookiename'] to call a cookie named cookiename
Value	Required Cookie value	This value is stored on the client and cannot be used to save sensitive data. If the name is 'cookiename', you can use $ _ COOKIE ['cookiename'] to obtain its value.
Expire	Optional Cookie expiration time	This is a Unix timestamp, that is, the number of seconds from the Unix epoch. In other words, the time () function and the number of seconds are usually used to set the cookie failure period. Or use mktime. Time () + 60*60*24*30 will set the cookie to expire after 30 days. If not set, the cookie will expire after the session ends (usually closed by the browser ).
Path	Optional valid Cookie path on the server	If this parameter is set to '/', the cookie is valid throughout the domain. if it is set to '/foo /', the cookie is valid only in the/foo/directory under the domain and its subdirectories, for example,/foo/bar /. The default value is the current directory of the cookie.
Domain	Optional domain name valid for this cookie	To make the cookie valid for all subdomains under the example.com domain name, set this parameter to '.example.com '. Although it is not necessary, it will be compatible with more browsers. If this parameter is set to www.example.com, it is valid only in the www subdomain. For details, see tail matching in Cookie specifications.
Secure	Optional. indicates whether the cookie is transmitted only through a secure HTTPS connection. When set to TRUE, the cookie is only set in secure connections. The default value is FALSE.
