MongoDB\Collection Class
Definition
Provides methods for common operations on collections and documents, including CRUD operations and index management.
You can construct collections directly using the extension's MongoDB\Driver\Manager class or select a collection from the library's [MongoDB\Client](https://www.mongodb.com/docs/php-library/current/reference/class/mongodbclient.md#mongodb-phpclass-phpclass.MongoDB-Client or [MongoDB\Database](https://www.mongodb.com/docs/php-library/current/reference/class/mongodbdatabase.md#mongodb-phpclass-phpclass.MongoDB-Database classes. A collection may also be cloned from an existing [MongoDB\Collection](https://www.mongodb.com/docs/php-library/current/reference/class/mongodbcollection.md#mongodb-phpclass-phpclass.MongoDB-Collection object by using the [withOptions()](https://www.mongodb.com/docs/php-library/current/reference/method/mongodbcollection-withoptions.md#mongodb-phpmethod-phpmethod.MongoDB-Collection--withOptions-- method.
[MongoDB\Collection](https://www.mongodb.com/docs/php-library/current/reference/class/mongodbcollection.md#mongodb-phpclass-phpclass.MongoDB-Collection supports the readConcern, readPreference, [typeMap](https://php.net/manual/en/mongodb.persistence.deserialization.php#mongodb.persistence.typemaps, and writeConcern options. If you omit an option, the collection inherits the value from the Manager constructor argument or the [Client](https://www.mongodb.com/docs/php-library/current/reference/class/mongodbclient.md#mongodb-phpclass-phpclass.MongoDB-Client or [Database](https://www.mongodb.com/docs/php-library/current/reference/class/mongodbdatabase.md#mongodb-phpclass-phpclass.MongoDB-Database object used to select the collection.
Operations within the [MongoDB\Collection](https://www.mongodb.com/docs/php-library/current/reference/class/mongodbcollection.md#mongodb-phpclass-phpclass.MongoDB-Collection class inherit the collection's options.
