Running your Symfony Application

On production, you should use a web server like Nginx or Apache (see configuring a web server to run Symfony). But for development, it's convenient to use the Symfony PHP web server.

Move into your new project and start the server:

1
2

$ cd my-project
$ php bin/console server:run

Open your browser and navigate to http://localhost:8000/. If everything is working, you'll see a welcome page. Later, when you are finished working, stop the server by pressing Ctrl+C from your terminal.

1

$ php bin/console server:start 0.0.0.0:8000

Storing your Project in git

Storing your project in services like GitHub, GitLab and Bitbucket works like with any other code project! Init a new repository with Git and you are ready to push to your remote:

1
2
3

$ git init
$ git add .
$ git commit -m "Initial commit"

Your project already has a sensible .gitignore file. And as you install more packages, a system called Flex will add more lines to that file when needed.

Setting up an Existing Symfony Project

If you're working on an existing Symfony application, you only need to get the project code and install the dependencies with Composer. Assuming your team uses Git, setup your project with the following commands:

1
2
3
4
5
6
7

# clone the project to download its contents
$ cd projects/
$ git clone ...

# make Composer install the project's dependencies into vendor/
$ cd my-project/
$ composer install

You'll probably also need to customize your .env and do a few other project-specific tasks (e.g. creating database schema).

Checking for Security Vulnerabilities

Symfony provides a utility called the "Security Checker" to check whether your project's dependencies contain any known security vulnerability. Check out the integration instructions for the Security Checker to set it up.

The Symfony Demo application

The Symfony Demo Application is a fully-functional application that shows the recommended way to develop Symfony applications. It's a great learning tool for Symfony newcomers and its code contains tons of comments and helpful notes.

To check out its code and install it locally, see symfony/symfony-demo.
