Sending and reading cookies in Yii_php example

cookies:

　 //The newly created cookie will be transferred from the local to the server, and then obtained from the server.

(1) Sending of cookies

　$cookies = Yii::$app->response->cookies;
　　 // 在要发送的响应中添加一个新的cookie
　　eg:往cookies中添加用户名和密码
　　$cookies->add(new Cookie(['name'=>'username', 'value'=>$username,]));
　　$cookies->add(new Cookie(['name'=>'password', 'value'=>$password,]));
　　//删除一个cookie
　　$cookies->remove('username');
　　//相当于
　　unset($cookies['username']);

(2) Cookie acquisition

$cookies = Yii::$app->request->cookies;
　　// 获取名为 "username" cookie 的值，如果不存在，返回默认值"en" 
　　$username = $cookies->getValue('username', 'en');
　　// 另一种方式获取名为 "username" cookie 的值
　　if (($cookie = $cookies->getValue('username')) !== null) {
　　　　$username = $cookie->value;
　　}
// 判断是否存在名为username的cookie
if (isset($cookies['username'])) {
$username= $cookies['username']->value;　　...
}if($cookies->has('username')){}
