Geohash
-------

[](#geohash)

Geohash is a php module that provides below functions.

- Encoding geographic location into short string of letters and digits.
- Decoding string of letters and digits to latitude and longitude.
- Identifying the neighbouring geohashes of a provided geohash.

Installation
------------

[](#installation)

The easiest way to install PHP Geohash is with [composer](https://getcomposer.org). Find it on [Packagist](https://packagist.org/packages/saikiran/geohash).

```
$ composer require saikiran/geohash

```

Usage
-----

[](#usage)

Encode co-ordinates

```
use Sk\Geohash\Geohash;

$g = new Geohash();
echo $g->encode(17.38000000, 78.42000000, 5);

```

The result is

```
tepfb

```

Decode geohash into geographical coordinates

```
use Sk\Geohash\Geohash;

$g = new Geohash();
$coordinates = $g->decode("tepfb", 5);
echo "latitude : " . $coordinates[0] . ",  longitude : " . $coordinates[1];

```

The result is

```
latitude : 17.38,  longitude : 78.42

```

Get geohashes of 8 neighbors of a geohash

```
use Sk\Geohash\Geohash;

$g = new Geohash();
$hash = $g->encode(25.813646, -80.133761, 7);
$neighbors = $g->getNeighbors($hash);
echo "Hash: $hash\n";
echo "Neighbors: " . json_encode($neighbors) . "\n";

```

The result is

```
Hash:
Neighbors: {"North":"dhx4be2","East":"dhx4be1","South":"dhx4bdb","West":"dhx4b7p","NorthEast":"dhx4be3","SouthEast":"dhx4bdc","SouthWest":"dhx4b6z","NorthWest":"dhx4b7r"}

```
