The most common way to set up cookies in PHP is to use the Setcookie function, Setcookie has 7 optional parameters, which we commonly used for the first 5:

Name (COOKIE name) can be accessed by $_cookie[' name ')
Value (values of the cookie)
Expire (expiry time) UNIX timestamp format, default = 0, indicates that the browser is off and is invalidated
Path (valid path) if the path is set to '/', the entire site is valid
Domain (valid domain) default entire domain name is valid, if ' www.imooc.com ' is set, it is only valid in WWW subdomain

$value = ' test '; Setcookie ("TestCookie", $value), Setcookie ("TestCookie", $value, Time () +3600);  Valid for one hour Setcookie ("TestCookie", $value, Time () +3600, "/path/", "imooc.com"); Set path and domain

PHP also has a function to set the cookie Setrawcookie,setrawcookie is basically the same as Setcookie, the only difference is that value values are not automatically urlencode, It is therefore necessary to manually carry out the urlencode when needed.

Because cookies are set by HTTP headers, they can also be set directly using the header method.

Header ("Set-cookie:cookie_name=value");
