How to Override Symfony's default Directory Structure

Symfony automatically ships with a default directory structure. You can easily override this directory structure to create your own. The default directory structure is:

your-project/
├─ assets/
├─ bin/
│  └─ console
├─ config/
├─ public/
│  └─ index.php
├─ src/
│  └─ ...
├─ templates/
├─ tests/
├─ translations/
├─ var/
│  ├─ cache/
│  ├─ log/
│  └─ ...
└─ vendor/

Override the cache Directory

You can change the default cache directory by overriding the getCacheDir() method in the Kernel class of your application:

// src/Kernel.php

// ...
class AppKernel extends BaseKernel
{
    // ...

    public function getCacheDir()
    {
        return dirname(__DIR__).'/var/'.$this->environment.'/cache';
    }
}

In this code, $this->environment is the current environment (i.e. dev). In this case you have changed the location of the cache directory to var/{environment}/cache.

Caution!

You should keep the cache directory different for each environment, otherwise some unexpected behavior may happen. Each environment generates its own cached configuration files, and so each needs its own directory to store those cache files.

Override the logs Directory

Overriding the logs directory is the same as overriding the cache directory. The only difference is that you need to override the getLogDir() method:

// src/Kernel.php

// ...
class AppKernel extends Kernel
{
    // ...

    public function getLogDir()
    {
        return dirname(__DIR__).'/var/'.$this->environment.'/log';
    }
}

Here you have changed the location of the directory to var/{environment}/log.

Override the Templates Directory

If your templates are not stored in the default templates/ directory, use the :ref:`twig.paths <config-twig-paths>` configuration option to define your own templates directory (or directories):

.. configuration-block::

    .. code-block:: yaml

        # config/packages/twig.yaml
        twig:
            # ...
            paths: ["%kernel.project_dir%/resources/views"]

    .. code-block:: xml

        <!-- config/packages/twig.xml -->
        <?xml version="1.0" ?>
        <container xmlns="http://symfony.com/schema/dic/services"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xmlns:twig="http://symfony.com/schema/dic/twig"
            xsi:schemaLocation="http://symfony.com/schema/dic/services
                http://symfony.com/schema/dic/services/services-1.0.xsd
                http://symfony.com/schema/dic/twig
                http://symfony.com/schema/dic/twig/twig-1.0.xsd">

            <twig:config>
                <twig:path>%kernel.project_dir%/resources/views</twig:path>
            </twig:config>

        </container>

    .. code-block:: php

        // config/packages/twig.php
        $container->loadFromExtension('twig', array(
            'paths' => array(
                '%kernel.project_dir%/resources/views',
            ),
        ));

Override the public Directory

If you need to rename or move your public directory, the only thing you need to guarantee is that the path to the var directory is still correct in your index.php front controller. If you simply renamed the directory, you're fine. But if you moved it in some way, you may need to modify these paths inside those files:

require_once __DIR__.'/../path/to/vendor/autoload.php';

You also need to change the extra.symfony-public-dir option in the composer.json file:

{
    "...": "...",
    "extra": {
        "...": "...",
        "symfony-public-dir": "my_new_public_dir"
    }
}

Tip

Some shared hosts have a public_html web directory root. Renaming your web directory from public to public_html is one way to make your Symfony project work on your shared host. Another way is to deploy your application to a directory outside of your web root, delete your public_html directory, and then replace it with a symbolic link to the public dir in your project.

Override the vendor Directory

To override the vendor directory, you need to define the vendor-dir option in your composer.json file like this:

{
    "config": {
        "bin-dir": "bin",
        "vendor-dir": "/some/dir/vendor"
    },
}

Tip

This modification can be of interest if you are working in a virtual environment and cannot use NFS - for example, if you're running a Symfony application using Vagrant/VirtualBox in a guest operating system.
