//设置cookie数组
$array_cookies
=
array
(

Careful people may find and read cookie in front of the assembly is slightly different, in front of all response->cookies, while the reading has spent request->cookies, and this is why? Can refer to the previous article by Yii framework response saved cookie, read cookie with a request of principle
Operating session
In Yii framework for the operation of the session, we are told something by a session component, we first need to get the assembly session.

|
$session
= \Yii::
$app
->session;
|
After obtaining the session component you want to operate on session, we first need to determine whether to enable session

if
(
$session
->isActive){
echo
"session已经开启"
;
}
else
{
$session
->open();
}
|
After the session has been opened, we can set and use the session data, first data session is set
|

|
$session
->set(
"user"
,
"张三"
);
|
Read session data is simple
|
1
|
$user
=
$session
->get(
"user"
);
|
Similarly, there are deleted session data
|
1
|
$session
->remove(
"user"
);
|
In addition, we can also be operated session as an array
