Yii

在组件中声明session 组件开启数据库库存储

[    'components' => [        'db'      => [            'class'         => 'yii\db\Connection',            'dsn'           => 'mysql:host=localhost;dbname=yii',            'username'      => 'root',            'password'      => 'xxxxxx',            'charset'       => 'utf8'        ],        'session' => [            'class' => 'yii\web\DbSession',  //session 操作对象            'db'    => 'db',     //指定数据库操作组件是上面的组件db            'sessionTable' => 'yii_session'  //session 数据库表名称        ]    ]]

yii_session 表结构

CREATE TABLE yii_session(    id CHAR(40) NOT NULL PRIMARY KEY,    expire INTEGER,    data BLOB)

namespace app\controllers\home;use Yii;use yii\web\Controller;class IndexController{    public function actionIndex()    {        $session = Yii::$app->session;        if(isset($session['name']) && isset($session['tel']))        {            var_dump($session);        }else{            $session['name'] = '谭勇';            $session['tel']  = 22;            echo 'set session';        }    }}
