Redbox-distance

This set of classes allow you to calculate the distance between Geo Locations or zipcodes. The information comes from the Google Maps API.

Features

Calculate the distance in
- Kilometers
- Miles
- Yards
Enable/Disable SSL Verifier
Set Google MAPS API key (Optional, its not required at this date May 25th of 2015)

Installing via Composer

Use composer to install this package. Run the Composer command to install the latest stable version of Redbox-distance:

composer require redbox/distance

After installing, you need to require Composer's autoloader:

require 'vendor/autoload.php';

System Requirements

This package only requires the following:

Curl
PHP >= 5.40

Dit will also require PHPUnit 4.6 but that will be installed upon installing the package using composer.

Examples

Lets calculate the distance between Amsterdam and Rotterdam (Netherlands) using GeoLocations:

use Redbox\Distance;

$p1 = new Distance\GeoPoint(52.364533, 4.820374); /* Amsterdam */
$p2 = new Distance\GeoPoint(51.925538, 4.471867); /* Rotterdam */


$tool = new Distance\CalculateDistance();
$distance = $tool->setSource($p1)
                 ->setDestination($p2)
                 ->setUseSslVerifier(false)
                 ->getDistanceInKM();

echo "<h2>Example 1</h2><br>";
echo 'The calculated distance is: '.$distance.' KM<br>';

Calculate the distance between Den Helder and Haarlem (Netherlands) using posalcodes:

use Redbox\Distance;

$p1 = new Distance\GeoZipCode('1781 GC'); /* Den Helder */
$p2 = new Distance\GeoZipCode("2011 SR"); /* Haarlem */


$tool = new Distance\CalculateDistance();
$distance = $tool->setSource($p1)
                 ->setDestination($p2)
                 ->setUseSslVerifier(false)
                 ->getDistanceInKM();

echo "<h2>Example 2</h2><br>";
echo 'The calculated distance is: '.$distance.' KM';

Other available calculations are:

$distance->getDistanceInMiles();

and

$distance->getDistanceInYards();

Troubleshooting

If you get an error regarding SSL connectivity you might want to disable verify peer (CURLOPT_SSL_VERIFYPEER). The calculateDistance class offers a method to disable this. Consider using the setUseSslVerifier() method if needed like so.

$distance = $tool->setSource($p1)
                 ...
                 ->setUseSslVerifier(false)
                 ...

Sometimes the postalcode feature could return wrong results. To battle this also add the country to the postalcode like so.

$p1 = new GeoZipCode('1781 GC Netherlands'); /* Den Helder */
