Your options extensions can live in a .proto file in the location of your choosing. protoc doesn't need to know about your options: it will simply parse the options into the UninterpretedOptions message. Then in the .proto files where you want to use your options, you need to put the option names in parentheses to indicate that they are extensions, not regular fields defined within FileOptions: option (php_namespace) = "...";
