Overview
--------

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/>`__.

This guide covers the following topics:

- :ref:`laravel-connection-auth-options`
- :ref:`laravel-driver-options`

Connection and Authentication Options
-------------------------------------

Learn how to add common connection and authentication options to your
configuration file in the following sections:

- :ref:`laravel-connection-auth-example`
- :ref:`laravel-connection-auth-descriptions`

.. _laravel-connection-auth-example:

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 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',

.. _laravel-connection-auth-descriptions:

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

* - **appName**
- String
- None
- | Specifies the application name that the {+php-library+} sends the
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**
- String
- 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
- ``false``
- Requests acknowledgment that the operation propagated to the on-disk
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 before 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's
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**
- String
- ``primary``
- Specifies how the {+php-library+} routes a read operation to replica set
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``
- Specifies whether the {+php-library+} retries a read operation if the operation fails.

* - **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+}
presents to the server to verify its identity.
| If you do not set this option, the {+php-library+} does not
attempt to verify its identity with the server.

* - **tlsInsecure**
- 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.

* - **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.
| Setting a value of ``-1`` selects the default compression level (``6``).
| Setting a value of ``0`` specifies no compression, and setting
a value of ``9`` specifies maximum compression.

To see a full list of connection options, see the :manual:`Connection String Options
</reference/connection-string/#connection-string-options>` section of the
Connection Strings guide in the {+server-docs-name+}. Select ``PHP`` from the
:guilabel:`Select your language` dropdown menu on the right side of the page.

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 <https://www.mongodb.com/docs/php-library/current/reference/method/MongoDBClient__construct/#parameters>`__
section of the {+php-library+} documentation for a list of driver options.
