Utilisation des COOKIES et SESSION dans Yii2.0

<?php
//第一种方法
$cookie = new /yii/web/Cookie();
$cookie -> name = &#39;smister&#39;;//cookie的名称
$cookie -> expire = time() + 3600; //存活的时间
$cookie -> httpOnly = true; //无法通过js读取cookie
$cookie -> value = &#39;cookieValue&#39;; //cookie的值
/Yii::$app->response->getCookies()->add($cookie);
//第二种方法
$cookie = new /yii/web/Cookie([
‘name&#39; => ‘smister&#39;,
‘expire&#39; => time() + 3600,
‘httpOnly &#39; => true,
‘value&#39; => ‘cookieValue&#39;
]);
/Yii::$app->response->getCookies()->add($cookie);
?>

<?php
$cookie = /Yii::$app->request->cookies;
//返回一个/yii/web/Cookie对象
$cookie->get(‘smister&#39;);
//直接返回Cookie的值
$cookie->getValue(‘smister&#39;); //$cookie[‘smister&#39;] 其实这样也是可以读取的
//判断一个Cookie是否存在
$cookie->has(‘smister&#39;);
//读取Cookie的总数
$cookie->count();//$cookie->getCount();跟count一样
?>

<?php
$cookie = Yii::$app->request->cookies->get(‘smister&#39;);
//移除一个Cookie对象
/Yii::$app->response->getCookies()->remove($cookie);
//移除所有Cookie，目前好像不太好使
/Yii::$app->response->getCookies()->removeAll();
?>

<?php
$session = /Yii::$app->session;
$session->set(&#39;smister_name&#39; , &#39;myname&#39;);
$session->set(&#39;smister_array&#39; ,[1,2,3]);
?>

<?php
$session = /Yii::$app->session;
//读取一个Session
$session->get(&#39;smister_name);
?>

<?php
$session = /Yii::$app->session;
//删除一个session
$session->remove(‘smister_name&#39;);
//删除所有session
$session->removeAll();
?>
