Distance class

Get distance between two locations using PHP. The distance is getting calculated based on latitude and logitude variables and without using any other external class.

Usage

Installing using Composer

When using Composer you can always load in the latest version.

{
    "require": {
        "jeroendesloovere/distance": "1.0.*"
    }
}

Check in Packagist.

Example

Setting our example data

use JeroenDesloovere\Distance\Distance;

// first location
$latitude1 = '50.8538510000';
$longitude1 = '3.3550450000';

// second location
$latitude2 = '50.8325600000';
$longitude2 = '3.4787650000';

Get distance between two locations

$distance = Distance::between(
    $latitude1,
    $longitude1,
    $latitude2,
    $longitude2
);

// dump data
echo 'Distance between the two locations = ' . $distance . ' km';

Get closest distance from location 1 to one of the two locations (2 and 3)

// third location
$latitude3 = '50.8865040000';
$longitude3 = '3.4320850000';

// define multiple items
$items = array(
    array(
        'title' => 'location 2',
        'latitude' => $latitude2,
        'longitude' => $longitude2
    ),
    array(
        'title' => 'location 3',
        'latitude' => $latitude3,
        'longitude' => $longitude3
    )
);

$distance = Distance::getClosest(
    $latitude1,
    $longitude1,
    $items
);

// dump data
echo 'The closest location to location 1 is ' . $distance['title'] . ' and the distance between them is ' . $distance['distance'] . ' km';

Documentation

The class is well documented inline. If you use a decent IDE you'll see that each method is documented with PHPDoc.
