Usage Examples

Run a Command

On this page

  • Example

You can run a MongoDB command directly on a database by calling the command() method on a database connection instance.

To run a command, call the command() method and pass it a document that contains the command and its parameters.

Example

This usage example performs the following actions on the database connection instance that uses the sample_mflix database:

  • Creates a database connection instance that references the sample_mflix database

  • Specifies a command to retrieve a list of collections and views in the sample_mflix database

  • Prints the value of the name field of each result returned by the command

The example calls the command() method to run the listCollections command. This method returns a cursor that contains a result document for each collection in the database.

$cursor = DB::connection('mongodb')
    ->command(['listCollections' => 1]);
foreach ($cursor as $coll) {
    echo $coll['name'] . "<br>\n";
}

To learn how to edit your Laravel application to run the usage example, see the Usage Examples landing page.
