I think Go is more foundational. If you can understand Go, you’ll mostly be able to learn PHP without problem; learning PHP is mostly endurance sport, via trial and error of using the builtins which are fairly unintuitive purely because of bad design. A strict PHP linter will speed up the process significantly though. Go is more like C on easy mode, but because C is so close to the kernel, you’ll likely learn a lot about Unix and the data structures by learning Go.
