README

Laravel Haversine is a package that provides utilities for calculating distances between geographical points using the Haversine formula. It includes a method that can be used with Laravel's Eloquent ORM to easily calculate distances between database records and a given point.

Installation

You can install the package via Composer. Run the following command in your terminal:

composer require iroid/laravel-haversine

The package will automatically register itself.

Usage

Calculating Distance

You can use the Haversine::distance() method to calculate the distance between two geographical points using the Haversine formula. This method returns the distance in kilometers by default.

use Iroid\LaravelHaversine\Haversine;

$latitudeFrom = 40.7128; // Latitude of point A
$longitudeFrom = -74.0060; // Longitude of point A
$latitudeTo = 34.0522; // Latitude of point B
$longitudeTo = -118.2437; // Longitude of point B

$distanceInKm = Haversine::distance($latitudeFrom, $longitudeFrom, $latitudeTo, $longitudeTo);

Using Different Units

You can specify the unit of measurement for the distance by passing an additional parameter to the distance() method. Supported units include kilometers (default), miles, nautical miles, and meters.

$distanceInMiles = Haversine::distance($latitudeFrom, $longitudeFrom, $latitudeTo, $longitudeTo, 'miles');
$distanceInNauticalMiles = Haversine::distance($latitudeFrom, $longitudeFrom, $latitudeTo, $longitudeTo, 'nautical_miles');
$distanceInMeters = Haversine::distance($latitudeFrom, $longitudeFrom, $latitudeTo, $longitudeTo, 'meters');

Using with Laravel Eloquent

You can use the applyHaversine() method provided by the package with Laravel's Eloquent ORM to calculate distances between database records and a given geographical point.

use Iroid\LaravelHaversine\Haversine;

$latitudeFrom = 40.7128; // Latitude of the reference point
$longitudeFrom = -74.0060; // Longitude of the reference point

// Example: Retrieving places sorted by distance from the reference point
$places = Place::applyHaversine($latitudeFrom, $longitudeFrom)
                ->orderBy('distance')
                ->get();

Parameters for applyHaversine()

• $query: The Eloquent query builder instance.
• $latitudeFrom: Latitude of the reference point.
• $longitudeFrom: Longitude of the reference point.
• $latitudeColumn (optional): Custom column name for latitude in the database table. Defaults to 'latitude'.
• $longitudeColumn (optional): Custom column name for longitude in the database table. Defaults to 'longitude'.
• $unit (optional): Unit of measurement for the distance. Supported units are kilometers (default), miles, nautical miles, and meters.

You can use these parameters to customize the behavior of the applyHaversine() method according to your database schema and requirements.
