MongoDB PHP Library 1.7.0 Released

The PHP team is happy to announce that version 1.7.0 of the MongoDB PHP library is now available. This library is a high-level abstraction for the mongodb extension. This release adds support for new features in MongoDB 4.4.

Release Highlights

New Client::listDatabaseNames and Database::listCollectionNames() methods allow enumeration of database and collection names without returning additional metadata. In the case of collection enumeration, this leverages the nameOnly option for listCollections and avoids taking a collection-level lock on the server.

Client::listDatabases() now supports an authorizedDatabases option, which can be used with MongoDB 4.0.5 or newer.

The Collection::deleteOne(), deleteMany(), and findOneAndDelete() methods now support a hint option to specify an index that should be used for the query. This option is also supported for delete operations in bulk writes. This option requires MongoDB 4.4 or later.

The Collection::findOneAndReplace() and findOneAndUpdate() methods now support a hint option, which requires MongoDB 4.2.

Collection::createIndex() and createIndexes() now support a commitQuorum option, which can be used with MongoDB 4.4.

The MongoDB\Operation\Aggregate class now implements the MongoDB\Operation\Explainable interface and can be used with Collection::explain(). This is an alternative to the explain option supported by Collection::aggregate() and allows for more verbose output when explaining aggregation pipelines.

The Client constructor now supports a driver option in its $driverOptions parameter, which can be used by wrapping drivers and libraries to append metadata (e.g. name and version) to the server handshake. The PHP library will also now append its own name and version to the metadata reported by the mongodb extension. Note that this feature is primarily designed for custom drivers and ODMs, which may want to identify themselves to the server for diagnostic purposes. Applications should use the appName URI option instead of driver metadata.

This release upgrades the mongodb extension requirement to 1.8.0. Support for PHP 5.6 has been removed and the library now requires PHP 7.0 or newer.
