[Flow] Own Constant into YAML Configuration

Not sure whether I got your question right..
With the %<CONSTANT>% syntax you can refer to PHP constants from within 
your settings (see [1]).

You can't set PHP Constants from the "outside" AFAIK. You *could* 
however use the "auto_prepend_file" directive [2] to include a file that 
sets the constant, but that seems a bit hacky to me.

As to *environment variables*: You can't *set* those via the settings, 
but for instance through a "SetEnv" option for apache:
SetEnv SOME_CONSTANT SomeValue

You can't access those in the settings though..
Could you elaborate on what you're trying to achieve?
