=======

Simple php geohash class like python-geohash.

Getting Started
---------------

[](#getting-started)

### Install

[](#install)

composer require lvht/geohash

### System Requirements

[](#system-requirements)

You need **PHP >= 5.4.0**.

### Usage

[](#usage)

Encode a coordinate:

```
use Lvht\GeoHash;
echo GeoHash::encode(117.031689,36.65396);

```

The result is wwe0x0euu12.

The default precision is 0.00001 which can be changed by the third parameter of encode method.

Find the neighbors for a given geohash:

```
use Lvht\GeoHash;
var_dump(GeoHash::expand('wwe0x0'));

```

and the result is:

```
array(8) {
  [0] =>
  string(11) "wwe0wc7zzzz"
  [1] =>
  string(11) "wwe0x17zzzz"
  [2] =>
  string(11) "wwe0x37zzzz"
  [3] =>
  string(11) "wwe0wb7zzzz"
  [4] =>
  string(11) "wwe0x27zzzz"
  [5] =>
  string(11) "wwe0qz7zzzz"
  [6] =>
  string(11) "wwe0rp7zzzz"
  [7] =>
  string(11) "wwe0rr7zzzz"
}

```

Decode a geohash string:

```
Use Lvht\GeoHash;
var_dump(GeoHash::decode('wwe0x0'));

```

and the result is:

```
array(4) {
  [0] =>
  double(117.0263671875)    # min longitude
  [1] =>
  double(117.03735351562)   # max longitude

  double(36.650390625)      # min latitude
