MongoDB\Driver\Manager::selectServer — Select a server matching a read preference

Descripción

final public MongoDB\Driver\Manager::selectServer(?MongoDB\Driver\ReadPreference $readPreference = null): MongoDB\Driver\Server

Selects a MongoDB\Driver\Server matching readPreference. If readPreference is null or omitted, the primary server will be selected by default. This may be used to preselect a server in order to perform version checking before executing an operation.

Nota: Unlike MongoDB\Driver\Manager::getServers(), this method will initialize database connections and perform server discovery if necessary. See the » Server Selection Specification for additional information.
