I have some bad experience with the Spyc parser Symfony uses for YAML,
namely having to raise my memory_limit to more than 128mb to get it
working with some YAML files.
I haven't dug into it's code, but thinking that Symfony sometimes uses
it on-line (and not only for CLI), got me kind of scared.
I think that while YAML is nice and easy to read/write (for humans),
there is only that much you can go for your lazy users - and while I
hate writing XML, I see it as a much better option for configuration
files (for now) because PHP has native, super-fast parsing abilities for
it. Writing a parser for YAML or any other format in PHP will have major
performance drawbacks any way you put it.
Unless YAML language and configuration files are translated off-line
into some kind of faster format (XML or even better, PHP code) I won't
use them in production.
Then again, that doesn't mean it shouldn't be an option ;)
