haversineDistance

Calculate the distance between two points using the Haversine Formula.

See Haversine_formula#Formulation.

use Esi\Utility\Conversion;

$lat1 = 37.774_9;
$lon1 = -122.419_4;
$lat2 = 34.052_2;
$lon2 = -118.243_7;

$result = Conversion::haversineDistance($lat1, $lon1, $lat2, $lon2);

print_r($result);
