Creating and Running Symfony Projects
ServBay is a local web development environment designed specifically for macOS and Windows. It comes integrated with runtimes for PHP, Node.js, Python, Go, Java, as well as databases such as MySQL, PostgreSQL, MongoDB, Redis, and supports both Apache and Caddy web servers. This guide walks you through setting up and running a Symfony project quickly on macOS and Windows using ServBay.
What is Symfony?
Symfony is an open-source PHP web framework created by SensioLabs, aimed at providing developers with a highly efficient, flexible, and robust set of tools for building modern web applications and APIs. It follows standard web best practices and offers a wealth of feature-rich components, such as routing, template engine (Twig), form handling, authentication, dependency injection, and more, greatly simplifying common web development tasks.
Key Features and Advantages of Symfony
- Modular Design: At its core, Symfony provides a reusable component library, enabling developers to select and utilize components as needed, whether building lightweight or enterprise-grade applications.
- High Performance: Optimized architecture, effective caching, and support for the latest PHP features ensure outstanding performance.
- Strong Community Support: A large developer community, rich third-party bundles (plugins), and comprehensive documentation make it easy to find solutions to your problems.
- Flexibility: Effortless integration with a variety of third-party libraries and extensions, suitable for projects of all sizes and complexities.
- Stability and Maintainability: By following best coding standards and design patterns, applications built on Symfony are easier to test, maintain, and extend.
Symfony is well-suited for building a diverse range of web projects, from small APIs to large-scale enterprise systems.
Creating and Running a Symfony Project with ServBay
ServBay provides a fully-supported environment for running Symfony projects, complete with the necessary PHP version, Composer, web server, and various databases and cache services. This section will guide you through using ServBay’s features to create and configure a new Symfony project.
Prerequisites
Before starting, please ensure you have fulfilled the following:
- ServBay Installed: ServBay has been successfully installed and launched on your macOS system. If not yet installed, refer to the ServBay Installation Guide.
- ServBay Running Properly: Core ServBay services (such as Caddy or Apache, and any required database) are up and running.
- Basic Understanding: You have a foundational knowledge of PHP, Composer, and basic Symfony concepts.
Creating a Symfony Project
ServBay recommends storing your site projects under the /Applications/ServBay/www
directory, making it easier for ServBay to detect and manage your projects.
Verify Composer Availability
ServBay includes Composer by default and sets up the required environment variables; you do not need a separate installation. In your terminal, type
composer --version
to confirm that Composer is ready to use.Create a Project Directory
Create a new directory in the recommended site root where your Symfony project will reside:
bashcd /Applications/ServBay/www mkdir servbay-symfony-app
1
2Create a Symfony Project with Composer
Change into your newly created directory and use Composer to bootstrap a Symfony project skeleton based on
website-skeleton
. Thewebsite-skeleton
is a foundational template including common dependencies for traditional web applications.bashcd /Applications/ServBay/www/servbay-symfony-app composer create-project symfony/website-skeleton .
1
2This command downloads the core Symfony files and dependencies to your current directory.
Initial Configuration
Core Symfony project configuration is typically managed using environment variables stored in a .env
file at your project root.
Configure Environment Variables (
.env
)Open the
.env
file in your project’s root directory. This file contains environment-specific settings like database connection info, app secrets, etc. Modify or add configuration entries as needed for your setup.Ensure the following settings are correctly configured, or adjust them based on your ServBay environment:
dotenv# Example .env file APP_ENV=dev # Development environment APP_SECRET=your_secret_key # Replace with a unique random string for security # Database connection info (example uses MySQL, detailed below) # DATABASE_URL="mysql://db_user:db_password@127.0.0.1:3306/db_name?serverVersion=8.0&charset=utf8mb4" # DATABASE_URL="postgresql://db_user:db_password@127.0.0.1:5432/db_name?serverVersion=13&charset=utf8" # DATABASE_URL="sqlite:///%kernel.project_dir%/var/data.db"

8Replace
your_secret_key
with a secure random string. For database connections, ServBay’s default database user is usuallyroot
with the passwordpassword
(note: always change these defaults in production). We'll useservbay_symfony_app
as the sample database name.
Configuring the Web Server (ServBay Website)
To access your Symfony project via the browser, use ServBay’s "Website" feature to configure a local virtual host. The web root for Symfony projects is the public/
directory under your project folder.
Open the ServBay control panel, navigate to "Website" (or "Host" in older versions), and add a new site:
- Name: Give your site an easy-to-remember name, e.g.,
My Symfony Dev Site
. - Domain: Set a local development domain, e.g.,
servbay-symfony-test.local
. ServBay will automatically map it locally. - Website Type: Choose
PHP
. - PHP Version: Select a PHP version compatible with Symfony, preferably the latest stable one provided by ServBay, e.g.,
8.3
. - Website Root: This is crucial. For Symfony, the website root must point to the project’s
public/
directory. Set to/Applications/ServBay/www/servbay-symfony-app/public
.
After configuring, save and apply changes. ServBay will automatically update web server settings. By default, ServBay uses Caddy or Apache and will generate and trust SSL certificates for your local domain, allowing you to directly access via HTTPS.
For detailed steps, see Add Your First Website in ServBay.
Adding a Basic Example Route
To verify your website’s setup, let's add a simple route and controller that outputs text when you visit the root path.
Configure Routing (
config/routes.yaml
)Open
config/routes.yaml
and add the following to define a/
root route pointing to anindex
controller method:yaml# config/routes.yaml index: path: / controller: App\Controller\DefaultController::index
1
2
3
4Create Controller (
src/Controller/DefaultController.php
)In the
src/Controller/
directory, create a new PHP fileDefaultController.php
:php<?php // src/Controller/DefaultController.php namespace App\Controller; use Symfony\Component\HttpFoundation\Response; use Symfony\Component\Routing\Annotation\Route; class DefaultController { /** * @Route("/", name="index") */ public function index(): Response { // Return a simple HTTP response return new Response('Hello ServBay and Symfony!'); } }

18This code creates a basic controller class
DefaultController
with anindex
method linked to the website root/
via the@Route("/")
annotation. Visiting the root path will return an HTTP response containing "Hello ServBay and Symfony!".
Accessing the Website
Now, open your web browser and visit your configured ServBay domain, https://servbay-symfony-test.local
. If everything is set up correctly, you’ll see the following output:
Hello ServBay and Symfony!

This confirms your Symfony project is running successfully with ServBay’s web server. Remember, ServBay auto-configures HTTPS, so always use https://
.
Database and Cache Examples
Symfony typically uses Doctrine ORM for relational databases and the Symfony Cache component for caching and NoSQL databases. ServBay offers a variety of database services and related PHP extensions, making it simple to use them within your Symfony project.
Relational Database Examples (Doctrine ORM)
ServBay supports MySQL and PostgreSQL. Here’s how to configure and use these databases with Symfony.
Configure the Database Connection
In your project’s
.env
file, uncomment and modify theDATABASE_URL
line according to the database you’re using.- For MySQL: ServBay’s default MySQL user is
root
with passwordpassword
on port3306
. Adjust as needed for your setup.dotenv# .env DATABASE_URL="mysql://root:password@127.0.0.1:3306/servbay_symfony_app?serverVersion=8.0&charset=utf8mb4"
1
2 - For PostgreSQL: ServBay’s default PostgreSQL user is
root
with passwordpassword
on port5432
. Adjust as needed for your setup.dotenv# .env DATABASE_URL="postgresql://root:password@127.0.0.1:5432/servbay_symfony_app?serverVersion=13&charset=utf8"
1

Ensure the relevant database services (MySQL or PostgreSQL) are started via the ServBay control panel.
- For MySQL: ServBay’s default MySQL user is
Create the Database
If the
servbay_symfony_app
database does not exist, create it either manually via ServBay’s database management tools (like phpMyAdmin or pgAdmin, accessible from the ServBay panel), or use Symfony commands:bashphp bin/console doctrine:database:create
1Create Entity and Migration Files
In Symfony, you use Doctrine Entities to represent database tables. The Maker Bundle makes generating entities and migration files easy.
- Create an Entity (e.g.,
User
entity):bashFollow prompts to add fields, e.g.php bin/console make:entity User
1name
(string) andemail
(string, unique=yes). - Create Migration File: Based on entity changes, generate migration files:bashThis will create a migration SQL file under
php bin/console make:migration
1src/Migrations
for theusers
table.
- Create an Entity (e.g.,
Run Migrations
Execute migrations to apply database structure changes:
bashphp bin/console doctrine:migrations:migrate
1Add Example Database Operations
Update
src/Controller/DefaultController.php
to add example routes and methods showing how to use Doctrine for reading/writing data. You’ll need to injectEntityManagerInterface
.First, ensure your
DefaultController
constructor receivesEntityManagerInterface
:php<?php // src/Controller/DefaultController.php namespace App\Controller; use Symfony\Component\HttpFoundation\Response; use Symfony\Component\Routing\Annotation\Route; use Doctrine\ORM\EntityManagerInterface; // Import EntityManagerInterface use App\Entity\User; // Import User entity use Symfony\Component\HttpFoundation\JsonResponse; // For JSON responses class DefaultController { private $entityManager; // Dependency injection for EntityManagerInterface public function __construct(EntityManagerInterface $entityManager) { $this->entityManager = $entityManager; } /** * @Route("/", name="app_index") */ public function index(): Response { return new Response('Hello ServBay and Symfony!'); } // ... other methods ... }

Cache and NoSQL Example (Symfony Cache)
ServBay comes with Redis and Memcached, and related PHP extensions. You can directly use them with the Symfony Cache component.
Configure Cache Connection
In your
.env
file, specify your cache connection:- For Memcached: ServBay default Memcached port is
11211
.dotenvMake sure Memcached is started in the ServBay panel.# .env # ... other config ... CACHE_DSN=memcached://127.0.0.1:11211
