Open source PHP Framework Yii: Multi-database operations

In most cases, we will use the same type of database, just to relieve the pressure into master-slave or distributed form.

Statement

?

You can declare other database connections in the app config:

 
  Array (        ' db ' =>....//primary link         ' db1 ' =>...//from connection 1        ' DB2 ' =>...//from Connection 2    )    ...

Operation

In the code, two slave connections can be obtained through Yii::app ()->DB1 and Yii::app ()->db2.

Advanced operations

More advanced (automatic) master-slave database functionality will be implemented in 1.1.
