+--------
+
+In this guide, you can learn about connection, authentication, and driver
+options and how to specify them in your Laravel application's database
+connection configuration. Connection options are passed to the {+php-library+},
+which manages your database connections.
+
+To learn more about the {+php-library+}, see the
+`{+php-library+} documentation <https://www.mongodb.com/docs/php-library/current/>`__.

+Connection and Authentication Options
+-------------------------------------
+
+Learn how to add common connection and authentication options to your
+configuration file in the following sections.
+
+Add Connection and Authentication Options
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can specify connection or authentication options in your Laravel web
+application's ``config/database.php`` configuration file by using one of the
+following methods:
+
+- Add the setting and value as an array item in the ``options`` array item.
+- Append the setting and value as a query string parameter on the connection
+  string specified in the ``dsn`` array item.
+
+To specify an option in the ``options`` array, add its name and value value as
+an array item, as shown in the following example:
+
+.. code-block:: php
+   :emphasize-lines: 6-10
+
+   'connections' => [
+       'mongodb' => [
+           'dsn' => 'mongodb+srv://mongodb0.example.com/',
+           'driver' => 'mongodb',
+           'database' => 'sample_mflix',
+           'options' => [
+               'appName' => 'myLaravelApp',
+               'compressors' => 'zlib',
+               'zlibCompressionLevel' => 7,
+           ],
+       ],
+   ],
+
+To specify options as parameters in the connection string, use the following
+query string syntax formatting:
+
+- Add the question mark character, ``?``, to separate the host information
+  from the parameters.
+- Add the options by formatting them as ``<option>=<value>``.
+- Insert the ampersand character, ``&``, between each option and value pair
+  to separate them.
+
+The following setting example shows the connection string parameter syntax:
+
+.. code-block:: php
+
+   'dsn' => 'mongodb+srv://mongodb0.example.com/?appName=myLaravelApp&compressors=zlib',
+
+Option Descriptions
+~~~~~~~~~~~~~~~~~~~
+
+The following table describes a list of connection and authentication options
+and their default values:
+
+.. list-table::
+   :header-rows: 1
+   :widths: 30 12 12 46
+
+   * - Option Name
+     - Accepted Values
+     - Default Value
+     - Description

+         MongoDB deployment as part of the handshake.
+       | Specifying ``appName`` can help you identify activities related
+         to that application in the server logs.
+
+   * - **authMechanism**
+     - String
+     - None
+     - Specifies which authentication mechanism to use. If you do not
+       specify this option, the driver uses the default authentication
+       mechanism. To learn more, see :manual:`Authentication </core/authentication/>`
+       in the {+server-docs-name+}.
+
+   * - **authMechanismProperties**

+     - None
+     - Specifies more properties related to the authentication mechanism set in
+       the ``authMechanism`` option.
+
+   * - **authSource**
+     - String
+     - See description
+     - | Specifies the database used to authenticate.
+       | This option defaults to ``admin`` for SCRAM-based authentication
+         mechanisms, ``$external`` for the ``MONGODB-X509`` mechanism, and the
+         database name or ``$external`` for the ``PLAIN`` mechanism.
+
+   * - **compressors**
+     - A comma-separated list of strings
+     - None
+     - Specifies data compressors that the {+php-library+} uses to reduce the
+       amount of network data passed between MongoDB and your application in
+       the specified order.

+   * - **connectTimeoutMS**
+     - Non-negative integer
+     - ``10000`` (10 seconds)
+     - Specifies the connection timeout, in milliseconds, passed to each
+       underlying TCP stream when attempting to connect to the server.
+
+   * - **directConnection**
+     - Boolean
+     - ``false``
+     - Specifies whether to directly connect to a single host instead of
+       discovering and connecting to all servers in the cluster.
+
+   * - **heartbeatFrequencyMS**
+     - Integer greater than or equal to 500
+     - ``10000`` (10 seconds)
+     - Specifies the time in milliseconds that each monitoring thread
+       waits between performing server checks.
+
+   * - **journal**
+     - Boolean

+       journal.
+
+   * - **localThresholdMS**
+     - Non-negative integer
+     - 15
+     - | Specifies the time in milliseconds that the average round-trip time
+         between the driver and server can last compared to the shortest
+         round-trip time of all the suitable servers.
+       | A value of ``0`` indicates no latency window, so only the server with
+         the lowest average round-trip time is eligible.
+
+   * - **maxIdleTimeMS**
+     - Non-negative integer
+     - 0
+     - | Specifies the time in milliseconds that a connection can remain idle
+         in a connection pool the server closes it.
+       | A value of ``0`` indicates that the client does not close idle
+         connections.
+
+   * - **maxStalenessSeconds**
+     - ``-1``, or any integer greater than or equal to ``90``
+     - ``-1``
+     - | Specifies the maximum lag, in seconds, behind the primary node
+         that a secondary node can be considered for the given operation.
+       | This option's value must be at least ``90``, or the operation raises
+         an error. A value of ``-1`` means there is no maximum lag.
+
+   * - **maxPoolSize**
+     - Non-negative integer
+     - ``10``
+     - | Specifies the maximum number of connections that the {+php-library+}
+         can create in a connection pool for a given server.
+       | If you attempt an operation while the value of ``maxPoolSize``
+         connections are checked out, the operation waits until an
+         in-progress operation finishes and the connection returns to the pool.
+
+   * - **minPoolSize**
+     - Non-negative integer
+     - ``0``
+     - | Specifies the minimum number of connections available in a server'
+         connection pool at a given time.
+       | If fewer than ``minPoolSize`` connections are in the pool,
+         the server adds connections in the background up to the value of ``minPoolSize``.
+
+   * - **readConcernLevel**
+     - String
+     - None
+     - Specifies the default read concern for operations performed by the
+       {+php-library+}.
+       To learn more, see :manual:`Read Concern </reference/read-concern/>` in the {+server-docs-name+}.
+
+   * - **readPreference**

+       members.
+       To learn more, see :manual:`Read Preference </core/read-preference>` in the {+server-docs-name+}.
+
+   * - **readPreferenceTags**
+     - A list of comma-separated key-value pairs
+     - None
+     - Specifies which replica set members are considered for operations.  Each
+       instance of this key is a separate tag set. The driver checks each tag
+       set until it finds one or more servers with each tag.
+
+   * - **replicaSet**
+     - String
+     - None
+     - Specifies the name of the replica set the {+php-library+} connects to.
+
+   * - **retryReads**
+     - Boolean
+     - ``true``

+
+   * - **serverSelectionTimeoutMS**
+     - Non-negative integer
+     - ``30000`` (30 seconds)
+     - Specifies the time in milliseconds that {+php-library+} waits to
+       select a server for an operation before timing out.
+
+   * - **tls**
+     - Boolean
+     - ``false``
+     - | Specifies the TLS configuration for the {+php-library+} to use in its
+         connections with the server.
+       | By default, TLS is off.
+
+   * - **tlsAllowInvalidCertificates**
+     - Boolean
+     - ``false``
+     - | Specifies whether the {+php-library+} returns an error if the server
+         presents an invalid certificate.
+       | We recommend setting this option to ``true`` only in testing
+         environments to avoid creating security vulnerabilities in your
+         application.
+
+   * - **tlsCAFile**
+     - String
+     - See description
+     - | Specifies the path to the certificate authority (CA) file that
+         the {+php-library+} uses for TLS.
+       | If you do not specify this option, the driver uses the Mozilla
+         root certificates from the ``webpki-roots`` crate.
+
+   * - **tlsCertificateKeyFile**
+     - String
+     - None
+     - | Specifies the path to the certificate file that {+php-library+}

+       | We recommend setting this option to ``true`` only in testing
+         environments to avoid creating security vulnerabilities in your
+         application.
+
+   * - **w**
+     - Non-negative integer or string
+     - None
+     - | Requests acknowledgment that the operation has propagated to a
+         specific number or variety of servers.
+       | To learn more, see :manual:`Write Concern </reference/write-concern>`
+         in the Server manual.
+
+   * - **wTimeoutMS**
+     - Non-negative integer
+     - No timeout
+     - Specifies a time limit, in milliseconds, of the write concern.
+       If an operation has not propagated to the requested level within the
+       time limit, the {+php-library+} raises an error.
+
+   * - **zlibCompressionLevel**
+     - Integer between -1 and 9 (inclusive)
+     - ``-1``
+     - | Specifies the level field of the ``zlib`` compression if you use that compressor.

+
+Driver Connection Options
+-------------------------
+
+Driver options modify the behavior of the {+php-library+}, which manages
+connections and all operations between a Laravel application and MongoDB.
+
+You can specify driver options in your Laravel web application's
+``config/database.php`` configuration file. To add driver options,
+add the setting and value as an array item in the ``driverOptions`` array
+item, as shown in the following example:
+
+.. code-block:: php
+   :emphasize-lines: 6-9
+
+   'connections' => [
+         'mongodb' => [
+             'dsn' => 'mongodb+srv://mongodb0.example.com/',
+             'driver' => 'mongodb',
+             'database' => 'sample_mflix',
+             'driverOptions' => [
+                  'serverApi' => 1,
+                  'allow_invalid_hostname' => false,
+              ],
+         ],
+       // ...
+     ]
+
+See the `$driverOptions: array section <https://www.mongodb.com/docs/php-library/current/reference/method/MongoDBClient__construct/#parameters>`__
+of the {+php-library+} documentation for a list of driver options.
