Symfony Basic File Structure

The Basic File Structure

The path variables are defined in the sfProjectConfiguration and sfApplicationConfigurationclasses and stored in the sfConfig object.

Every path to a key directory is determined by a parameter ending with _dir. Always use the path variables instead of real (relative or absolute) file paths, so that you will be able to change them later, if necessary. For instance, when you want to move a file to the uploads/ directory in an application, you should use sfConfig::get('sf_upload_dir') for the path instead of
