MongoDB\Database::renameCollection()

Rename a collection within the current database.

function renameCollection(
    string $fromCollectionName,
    string $toCollectionName,
    ?string $toDatabaseName = null,
    array $options = []
): void

Parameters

$fromCollectionName : string

The name of the collection to rename.

$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 current database 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.

Name	Type	Description
comment	mixed	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.
dropTarget	boolean	If `true`, MongoDB will drop the target before renaming the collection. The default value is `false`.
session	MongoDB\Driver\Session	Client session to associate with the operation.
typeMap	array	The type map to apply to cursors, which determines how BSON documents are converted to PHP values. Defaults to the database's type map. This will be used for the returned command result document.
writeConcern	MongoDB\Driver\WriteConcern	Write concern to use for the operation. Defaults to the database's write concern.

Errors/Exceptions

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).

Example

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

<?php
$db = (new MongoDB\Client)->test;
$db->renameCollection('restaurants', 'places');
