Symfony2 Use PHP Class Constant in YAML Config?
php, symfony, yaml
Solution
In versions before Symfony 3.2, injecting PHP-constants only works with XML:
<parameter key="my_service.my_const" type="constant">My\Bundle\DependencyInjection\MyClass::MY_CONST</parameter>
If you want to keep yor yml files, you could just import the xml-file into your services.yml. Mixing config styles might be a bit ugly, but as far as I know this is the only way to do it.
If this doesn't work for you, my comment to your question applies.
Problem
I know this is probably not possible, but is there a clean way to use a PHP class constant within a YAML config/services/etc. file for Symfony2? For example, if I have this: ``` namespace My\Bundle\DependencyInjection; class MyClass { const MY_CONST = 'cookies'; } ``` Is something like this possible (in a .yml file): ``` services: my_service: class: Some\Class arguments: - %My\Bundle\DependencyInjection\MyClass::MY_CONST% ``` That'd go a long way in helping maintain consistency between the two.
