Ways to get the cookie expiration time
$expire = time () + 86400; Set the 24-hour validity period
Setcookie ("Var_name", "Var_value", $expire); Set a cookie named Var_name, and establish a validity period
Setcookie ("Var_name_expire", $expire, $expire); Then set the expiration time to a cookie so that you can know the expiration time of the Var_name

Note:
When a cookie is sent, the value of the cookie is automatically URL-encoded. The URL is decoded when it is received.
If you don't need this, you can use Setrawcookie () instead.
