Answer 1

Working solution in Symfony 3.3+

# app/config/config.yml
parameters:
    ...
    base_url: 'http://mywebsite.com'

To get it in your controller action:

$baseUrl = $this->getParameter('base_url');

You can now append your image to it e-g: $baseUrl . '/uploads/' . $image or if you like you can define uploaded assets base url in config.yml and access it in controller action.

Best thing about this solution would be the ability to pre-define it for different environments e-g: in config.yml, config_dev.yml and config_test.yml so when you move your project between different environments, you don't have to change it as it's already there..
