SQLSTATE[HY000] [1049] Unknown database 'yii2basic'

in W:\XAMPP\htdocs\basic\vendor\yiisoft\yii2\db\Connection.php at line 602

Answer 1

您应该在db.php配置文件中分配正确的值

在你的basic \ config目录中找到文件\ db.php，然后为数据库分配正确的值，用户名和密码

return [
   'class' => 'yii\db\Connection',
    'dsn' => 'mysql:host=localhost;dbname=yii2basic',
                                           ^^^ assign your correct dbname
    'username' => 'root',  // assign you  correct username  
     'password' => '',     // assign your password 
    'charset' => 'utf8',
 ];
