This tutorial is deprecated. It was written when Symfony2 was in beta. 

In Symfony 1.x a task is a command line tool to help perform tasks around the application. The same is in Symfony 2. Unfortunately in Symfony2 there is no tool to auto-generate some code for these. To create a Symfony2 Command you must to have or to create in your Bundle a folder named Command. Here, you must create a file named MytaskCommand.php with the following code:

 

<?php
namespace ApplicationVremeaBundleCommand;

use SymfonyBundleFrameworkBundleCommandCommand;
use SymfonyComponentConsoleInputInputDefinition;
use SymfonyComponentConsoleInputInputOption;
use SymfonyComponentConsoleInputInputArgument;
use SymfonyComponentConsoleInputInputInterface;
use SymfonyComponentConsoleOutputOutputInterface;
use SymfonyComponentRazvanUtilsCurl;

class ImportCommand extends Command {

 const NEWLINE = true;
 private $connection;

 protected function configure() {
 parent::configure();

 $this
                ->setName('tudorica:razvan')
                ->addArgument('type', InputArgument::REQUIRED, 'Type')
                ->addOption('country', 'c', InputOption::VALUE_OPTIONAL, 'Country', '')

        ;
    }

    /**
     * Executes the current command.
     *
     * @param InputInterface  $input  An InputInterface instance
     * @param OutputInterface $output An OutputInterface instance
     *
     * @return integer 0 if everything went fine, or an error code
     *
     * @throws LogicException When this abstract class is not implemented
     */
    protected function execute(InputInterface $input, OutputInterface $output) {
        // your code here.
        //if you want to access database (must to setup doctrine.dbal)
        $this->connection = $this->container->get('database_connection');

         //to get the user input argument "type" for this command
        $type = $input->getArgument('type');        

        //to get use option "contry" for this command
        $country = $input->getOption('country');

        //to write a message (in symfony1.x was named log).
        $output->write('type: '.$type, true);
    }

}

ow, you can open a console and go to app folder. If you write:

./console

you will see something like

router
  :debug                       Displays current routes for an application
  :dump-apache                 Dumps all routes as Apache rewrite rules
tudorica
  :razvan

You can execute this Command with: ./console tudorica:razvan
