How to create a custom yaml config file in Symfony

Question

What I want to do is quite simple: store data in a custom config file that I want to read later on.

I created my file something.yml that I put in the global

If you're doing this for a plugin you need to load the configuration file in the initialize() method. You can still use config_handlers.yml in your plugin's config directory or let the plugin load the handler too.

class myPluginConfiguration extends sfPluginConfiguration
{
  public function setup() // loads handler if needed
  {
    if ($this->configuration instanceof sfApplicationConfiguration)
    {
      $configCache = $this->configuration->getConfigCache();
      $configCache->registerConfigHandler('config/features.yml', 'sfDefineEnvironmentConfigHandler',
        array('prefix' => 'feature_'));
      $configCache->checkConfig('config/features.yml');
    }
  }

  public function initialize() // loads the actual config file
  {
    if ($this->configuration instanceof sfApplicationConfiguration)
    {
      $configCache = $this->configuration->getConfigCache();
      include($configCache->checkConfig('config/features.yml'));
    }
  }
}

The plugin's config initialize() method is called automatically by sfProjectConfiguration class and all appConfiguration classes (trough inheritance).
