Creating Symfony Project

You can create a new Symfony project using Symfony CLI or Composer command line tools.

Using Symfony CLI

To create a new Symfony project, you can use symfony new command.

$ symfony new rest-sample

// install a webapp pack 
$ symfony new web-sample --webapp

By default, it will create a simple Symfony skeleton project only with core kernel configuration, which is good to start a lightweight Restful API application.

To get full options list of symfony new command, type the following command in your terminal.

$ symfony help new
Description:
  Create a new Symfony project

Usage:
  symfony.exe local:new [options] [--] [<directory>]

Arguments:
  directory  Directory of the project to create


Options:
  --dir=value      Project directory
  --version=value  The version of the Symfony skeleton (a version or one of "lts", "stable", "next", or "previous")
  --full           Use github.com/symfony/website-skeleton (deprecated, use --webapp instead)
  --demo           Use github.com/symfony/demo
  --webapp         Add the webapp pack to get a fully configured web project
  --book           Clone the Symfony: The Fast Track book project
  --docker         Enable Docker support
  --no-git         Do not initialize Git
  --cloud          Initialize Platform.sh
  --debug          Display commands output
  --php=value      PHP version to use

Alternatively, you can create it using Composer.

Using Composer

Run the following command to create a Symfony project using composer.

# composer create-project symfony/skeleton rest-sample

//start a classic website application
# composer create-project symfony/website-skeleton web-sample

The later is similar to the symfony new projectname --full to generate a full-featured web project skeleton.

Running Application

Open your terminal, switch to the project root folder, and run the following command to start the application.

# symfony server:start

 [WARNING] run "symfony.exe server:ca:install" first if you want to run the web server with TLS support, or use "--no-  
 tls" to avoid this warning
