Description
readConcern
The default read concern to use for database operations. Defaults to the manager's read concern.
readPreference
The default read preference to use for database operations. Defaults to the manager's read preference.
typeMap
array

Default type map to apply to cursors, which determines how BSON documents are converted to PHP values. The library uses the following type map by default:

[
'array' => 'MongoDB\Model\BSONArray',
'document' => 'MongoDB\Model\BSONDocument',
'root' => 'MongoDB\Model\BSONDocument',
]
writeConcern
The default write concern to use for database operations. Defaults to the manager's write concern.

MongoDB\\Exception\\InvalidArgumentException for errors related to the parsing of parameters or options.

If you construct a Database explicitly, the Database inherits any options from the MongoDB\\Driver\\Manager object. If you select the Database from a Client object, the Database inherits its options from that object.
