i am just trying to foster discussion here. i am not looking for a job and I am not trying to bash PHP so hardcore PHP people do not need to get defensive.
I am not asking if it is worth it for me to learn PHP. I want to learn it because, like you said, it is good to know multiple languages and this fits in well with my current needs and environment.
As for a company not caring what language you know as long as you are good. That might be the case for a small company, but not one with 1000+ employees where they have a java development group. They are not going to hire a guy that only knows PHP no matter how good he might be in PHP.
Again, this is not an attack on PHP. Just a discussion!
