connect(array $parameters, boolean $selectDB = false)

Link this connector to the database given the specified parameters Will throw an exception rather than return a success state.

The connector should not select the database once connected until explicitly called by selectDatabase()

Parameters

array $parameters List of parameters such as

  • type
  • server
  • username
  • password
  • database
  • path
boolean $selectDB By default database selection should be handled by the database controller (to enable database creation on the fly if necessary), but some interfaces require that the database is specified during connection (SQLite, Azure, etc).
