README
Distical is a PHP distance calculator library of which, amongst other things is developed to calculate the distance between two or more lat/long coordinates.
License
This client library is released under the MIT license.
Requirements
This library is unit tested against PHP 7.3, 7.4, 8.0, 8.1 and 8.2!
If you need to use an older version of PHP, you should instead install the 3.x version of this library (see below for details).
Setup
I highly recommend the use of Composer when installing and using this library, it is not mandatory however and you can use a provided 'include' script to load in this library if required.
Composer
Simply require this package as follows:
composer require ballen/distical
If you need to use an older version of PHP, version 2.x.x supports PHP 5.3, 5.4, 5.5, 5.6, 7.0, 7.1 and 7.2, you can install this version using Composer with this command instead:
composer require ballen/disitcal ^2.0
composer install
Standalone
You can use the library "standalone" by downloading it from the GitHub releases section, extracting the files to a place on your server and then adding the "include" into your code like so:
require_once 'path/to/Distical/Distical.inc.php';
Examples
use Ballen\Distical\Calculator as DistanceCalculator; use Ballen\Distical\Entities\LatLong; // Set our Lat/Long coordinates $ipswich = new LatLong(52.057941, 1.147172); $london = new LatLong(51.507608, -0.127822); // Get the distance between these two Lat/Long coordinates... $distanceCalculator = new DistanceCalculator($ipswich, $london); // You can then compute the distance... $distance = $distanceCalculator->get(); // you can also chain these methods together eg. $distanceCalculator->get()->asMiles(); // We can now output the miles using the asMiles() method, you can also calculate and use asKilometres() or asNauticalMiles() as required! echo 'Distance in miles between Central Ipswich and Central London is: ' . $distance->asMiles();
A set of working examples including multi-point calculations can be found in the /examples
directory, feel free to browse or run them!
Tests and coverage
This library is fully unit tested using PHPUnit.
I use GitHub Actions for continuous integration, which triggers tests for PHP 7.3, 7.4, 8.0, 8.1 and 8.2 everytime a commit is pushed.
If you wish to run the tests yourself you should run the following:
# Install the Distical Library with the 'development' packages this then including PHPUnit!
composer install
# Now we run the unit tests (from the root of the project) like so:
./vendor/bin/phpunit
Code coverage can also be ran but requires XDebug installed...
./vendor/bin/phpunit --coverage-html ./report
