[](#php-proximity-hash-)

A port of [https://github.com/ashwin711/proximityhash](proximityhash) for PHP.

Geohash is a geocoding system invented by Gustavo Niemeyer and placed into the public domain. It is a hierarchical spatial data structure which subdivides space into buckets of grid shape, which is one of the many applications of what is known as a Z-order curve, and generally space-filling curves.

To visualize geohashes, you can go here :

ProximityHash generates a set of geohashes that cover a circular area, given the center coordinates and the radius.

Below is an illustration of what it looks like on a map :
