How to connect to the database in YII first?

Question

Yii

can't connect to db in YII
config:
'db'=>array(
'connectionString' => 'mysql:host=localhost;dbname=samos23_avenudev',
'emulatePrepare' => true,
'username' => 'samos23_avenudev',
'password ' => 'qwerty1234567890',
'charset' => 'utf8',
'tablePrefix' => 'tbl_',
),

Answer 1

The config is visually correct, go on Yii::app()->db-> ...and on)
If it doesn’t work, look at the mysql server settings, namely:
1. Is it exactly listening to localhost port 3306
2. Is it exactly what the database is called
3. Is the connection data correct
In general, in order not to guess, it would be nice to turn on debug and see what exception is thrown when the database is accessed.
