Geohash
Library to convert a geohash to/from a latitude/longitude point, and to determine bounds of a geohash cell and find neighbours of a geohash.
This is a PHP implementation based on chrisveness/latlon-geohash. More information (with interactive conversion) at www.movable-type.co.uk/scripts/geohash.html.
Usage
use Beste\Geohash;
// encode latitude/longitude point to geohash of given precision (number of
// characters in resulting geohash); if precision is not specified, it is
// inferred from precision of latitude/longitude values.
Geohash::encode(float $lat, float $lon, ?int $precision = null)
// return { lat, lon } of centre of given geohash, to appropriate precision.
Geohash::decode(string $geohash)
// return { sw, ne } bounds of given geohash.
Geohash::bounds(string $geohash)
// return adjacent cell to given geohash in specified direction (n/s/e/w).
Geohash::adjacent(string $geohash, string $direction)
// return all 8 adjacent cells (n/ne/e/se/s/sw/w/nw) to given geohash.
Geohash::neighbours(string $geohash)
