Find/Replace "rails" with "Symfony" and you'll have the PHP equivalent. Also, "bundles" instead of "gems". This is why PHP negativity has been increasingly misguided for the past 2 years.
In ruby, mostly everyone i know, uses rails and mostly everyone writes some test. either TDD or after writing the code.
It is not as bad as PHP but personally even for me, i should write better rails code
Any developer, PHP or otherwise, that knowingly ignores contributions within the community is dangerous :)
No matter what language you use, you can always write better code, even with PHP!
