Your "localhost" cannot resolve the name google.com to an ip address, which means your machine doesn't/can't reach a valid dns server.
This probably doesn't only affect php. Try ping google.com on the console of that machine. Does this complain about the unknown host, too?
The steps necessary to solve the problem depend on what your "localhost" is (operating system, flavour/distribution, ...) and how it is connected to the internet.
