PHP Coordinate

You work with geographic coordinates in different formats (sexagesimal, decimal). You want to parse or convert them. Then the following library could be the right one for you if you work within a PHP Composer project:

• PHP Coordinate

Easy to install via:

composer require ixnode/php-coordinate

You can then convert coordinates, parse, calculate distance, direction, etc:

Converter example

$coordinate = new Coordinate(51.0504, 13.7373);

print $coordinate->getLatitudeDMS();
// (string) 51°3′1.44″N

print $coordinate->getLongitudeDMS();
// (string) 13°44′14.28″E

Parser example

$coordinate = new Coordinate('51°3′1.44″N 13°44′14.28″E');

print $coordinate->getLatitude();
// (float) 51.0504

print $coordinate->getLongitude();
// (float) 13.7373

Distance example

$coordinateDresden = new Coordinate('51°3′1.44″N 13°44′14.28″E');
$coordinateCordoba = new Coordinate(-31.425299, -64.201743);

/* Distance between Dresden, Germany and Córdoba, Argentina */
print $coordinate->getDistance($coordinateCordoba, Coordinate::RETURN_KILOMETERS);
// (float) 11904.668

Direction example (degree)

$coordinateDresden = new Coordinate('51°3′1.44″N 13°44′14.28″E');
$coordinateCordoba = new Coordinate(-31.425299, -64.201743);

/* Direction in degrees from Dresden, Germany to Córdoba, Argentina */
print $coordinateDresden->getDegree($coordinateCordoba);
// (float) -136.62°

Direction example (cardinal direction)

$coordinateDresden = new Coordinate('51°3′1.44″N 13°44′14.28″E');
$coordinateCordoba = new Coordinate(-31.425299, -64.201743);

/* Direction in degrees from Dresden, Germany to Córdoba, Argentina */
print $coordinateDresden->getDirection($coordinateCordoba);
// (string) SW

Finally
