The PHP Distance library allows for calculation of many types of distance between points.
PHP Distance can be easily installed using Composer. Just run the following command from the root of your project.
composer require divineomega/php-distance
If you have never used the Composer dependency manager before, head to the Composer website for more information on how to get started.
See the following code snippet that demonstates how to use this library.
$a = new Point($x1, $y1);
$b = new Point($x2, $y2);
$c = new Point($x3, $y3, $z3); # Infinite dimensions supported by some distance types
$distanceType = new Euclidean();
$distanceType = new EuclideanSquare();
$distanceType = new Haversine(); # For GPS coordinates (latitude and longitude)
$distance = (new Distance())
->type(new Euclidean()) # Type is optional, and defaults to Euclidean distance
->from($a)
->to($b)
->get();
