New in version 1.10.


Rename the collection.

function rename(
string $toCollectionName,
?string $toDatabaseName = null,
array $options = []
): array|object
$toCollectionName : string
The new name of the collection.
$toDatabaseName : string
The new database name of the collection. If a new database name is not specified, the database of the original collection will be used. If the new name specifies a different database, the command copies the collection to the new database and drops the source collection.
$options : array

An array specifying the desired options.

If true, MongoDB will drop the target before renaming the collection. The default value is false.

Enables users to specify an arbitrary comment to help trace the operation through the database profiler, currentOp output, and logs.

This option is available since MongoDB 4.4 and will result in an exception at execution time if specified for an older server version.

New in version 1.13.


Client session to associate with the operation.


The type map to apply to cursors, which determines how BSON documents are converted to PHP values. Defaults to the collection's type map.

This will be used for the returned command result document.


Write concern to use for the operation. Defaults to the collection's write concern.

It is not possible to specify a write concern for individual operations as part of a transaction. Instead, set the writeConcern option when starting the transaction.

An array or object with the result document of the renameCollection command. The return type will depend on the typeMap option.

MongoDB\Exception\UnsupportedException if options are used and not supported by the selected server (e.g. collation, readConcern, writeConcern).

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

MongoDB\Driver\Exception\RuntimeException for other errors at the extension level (e.g. connection errors).

The following operation renames the restaurants collection in the test database to places:

$collection = (new MongoDB\Client)->test->restaurants;
$result = $collection->rename('places');

The output would then resemble:

object(MongoDB\Model\BSONDocument)#9 (1) {
array(1) {
