+SSL Connection with MySQL
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to configure a secure SSL connection to MySQL in your Symfony application using Doctrine, you need to set specific options for the SSL certificates. Here's how to configure the connection using environment variables for the certificate paths:
+
+.. configuration-block::
+
+    .. code-block:: yaml
+
+        doctrine:
+            dbal:
+                url: '%env(DATABASE_URL)%'
+                server_version: '8.0.31'
+                driver: 'pdo_mysql'
+                options:
+                    # SSL private key (PDO::MYSQL_ATTR_SSL_KEY)
+                    1007: '%env(MYSQL_SSL_KEY)%'
+                    # SSL certificate (PDO::MYSQL_ATTR_SSL_CERT)
+                    1008: '%env(MYSQL_SSL_CERT)%'
+                    # SSL CA authority (PDO::MYSQL_ATTR_SSL_CA)
+                    1009: '%env(MYSQL_SSL_CA)%'
+
+    .. code-block:: xml
+
+        <?xml version="1.0" encoding="UTF-8" ?>
+        <container xmlns="http://symfony.com/schema/dic/services"
+            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+            xmlns:doctrine="http://symfony.com/schema/dic/doctrine"
+            xsi:schemaLocation="http://symfony.com/schema/dic/services
+                https://symfony.com/schema/dic/services/services-1.0.xsd
+                http://symfony.com/schema/dic/doctrine
+                https://symfony.com/schema/dic/doctrine/doctrine-1.0.xsd">
+
+            <doctrine:config>
+                <doctrine:dbal
+                    url="%env(DATABASE_URL)%"
+                    server-version="8.0.31"
+                    driver="pdo_mysql">
+
+                    <doctrine:option key="1007">%env(MYSQL_SSL_KEY)%</doctrine:option>
+                    <doctrine:option key="1008">%env(MYSQL_SSL_CERT)%</doctrine:option>
+                    <doctrine:option key="1009">%env(MYSQL_SSL_CA)%</doctrine:option>
+                </doctrine:dbal>
+            </doctrine:config>
+        </container>
+
+Make sure that your environment variables are correctly set in your ``.env.local`` or ``.env.local.php`` file as follows:
+
+.. code-block:: bash
+
+    MYSQL_SSL_KEY=/path/to/your/server-key.pem
+    MYSQL_SSL_CERT=/path/to/your/server-cert.pem
+    MYSQL_SSL_CA=/path/to/your/ca-cert.pem
+
+This configuration secures your MySQL connection with SSL by specifying the paths to the required certificates.
