The **PHP Geohash Generator** is a simple yet powerful tool that converts geographic coordinates (latitude and longitude) into a compact and highly useful **geohash** string. Perfect for efficiently storing, searching, and managing spatial data in your applications! 🚀

---

What is a Geohash? 🤔
--------------------

[](#what-is-a-geohash-)

A geohash is an algorithm that divides the Earth into progressively smaller "boxes" and encodes the coordinates as a text string.

- **In short:** A geohash is a single string representation of a specific location on Earth.
- **Benefits:**
    - Compact and human-readable format.
    - Easy to compare: if two locations are close, their geohashes share the same prefix.
    - Ideal for fast searches and spatial grouping.

---

Why use this library? 🎯
-----------------------

[](#why-use-this-library-)

- **Easy to use**: Simply provide latitude and longitude, and get a geohash in return.
- **Precision-focused**: The algorithm supports up to 12-character geohashes for highly accurate encoding.
- **Perfect for location-based applications**: Whether storing spatial data, searching for locations, or displaying maps, this tool gets the job done efficiently.

Installation & Usage 🛠️
---------------------------

[](#installation--usage-️)

> **Requires [PHP 8.3+](https://php.net/releases/)**

```
composer require igzard/php-geohash
```

```
use Igzard\Geohash\Geohash;

// Generate a geohash for a specific location with latitude and longitude coordinates.
echo Geohash::generate(47.497913, 19.040236); // input: Budapest coordinates | output: u2mw1q8xmssz

// Generate a geohash with custom precision (default is 12), latitude interval, and longitude interval.
echo Geohash::generate(47.497913, 19.040236, [
    'precision' => 10,
    'latitude_interval' => [
        'min' => -70,
        'max' => 10,
    ],
    'longitude_interval' => [
        'min' => -80,
        'max' => 170,
    ],
]);
```
