How to create a command (task) in Symfony 2

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:

namespace Application\VremeaBundle\Command;

use Symfony\Bundle\FrameworkBundle\Command\Command;
use Symfony\Component\Console\Input\InputDefinition;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Razvan\Utils\Curl;

class ImportCommand extends Command {

 const NEWLINE = true;
 private $connection;

 protected function configure() {

                ->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);


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


you will see something like

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

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

Public, Private, and Protected in PHP

or how to manage access to your classes.

In PHP there are three levels of access for properties and methods from within a class: public, private, and protected.

Public access is the default setting for method and for properties.

  • Public properties and methods can be accessed from any context.
  • Private methods and properties can ONLY be accessed from within the enclosing class. The subclasses have no access to them.
  • Protected methods and properties can be accessed from within the enclosing class and from subclasses.

According with Zend Coding Standards, variables that are declared with the “private” or “protected” modifier, the first character of the variable name must be a single underscore.

eg: private $_myVar;
