使用setcookie()函数可以在PHP中设置Cookie。
setcookie(name, value, expire, path, domain, secure, httponly);$name = "username";
$value = "Tom";
$expire = time() + 3600;
$path = "/";
$domain = ".example.com";
$secure = true;
$httponly = true;
setcookie($name, $value, $expire, $path, $domain, $secure, $httponly);以上代码会在example.com域名下设置名为"username"，值为"Tom"的Cookie，过期时间为一小时后，只能通过HTTPS协议访问，不能通过JavaScript访问。
