[tags]symfony, yaml, configuration, web debug, debug[/tags] There's no doubt that yaml configuration files in symfony can be troublesome to debug.
The symfony web debugger comes to the rescue.
Let's say you're app.yml has the following:
app:
admin:
email: me@example.com
In your development environment you can look at click on "vars & config" and under settings see all the sfConfig::getable variables. You'll find the above listed as:
app_admin_email: me@example.com
This technique is very handy when trying to figure out what key you need to use in sfConfig::get().
