MongoDB\Database Class

On this page



Provides methods for common operations on a database, such as executing database commands and managing collections.

You can construct a database directly using the driver’s MongoDB\Driver\Manager class or select a database from the library’s MongoDB\Client class. A database may also be cloned from an existing MongoDB\Database object via the withOptions() method.

MongoDB\Database supports the readConcern, readPreference, typeMap, and writeConcern options. If you omit an option, the database inherits the value from the Manager constructor argument or the Client object used to select the database.

Operations within the MongoDB\Database class inherit the Database’s options.
