PostGIS would be worth it if there was a lot more to do on that project and full respect to that project. I remember looking at it and it felt like it was a sledgehammer for that particular job. You still had to write up a lot of code to import the dataset you had and then extract it again. Not to mention maintenance since you now have a whole dependency chain installed on your server. This was a single engineer project. The above solution is a copy paste-able set of classes with zero dependencies that will output the nearest place. Sometimes a single purpose solution is perfect and i'm really not kidding when i say i haven't maintained or even looked at it in over 5 years yet it's still running fine as part of a larger application.
