Retrieve bounding coordinates and distances with GeoLocation.php

GeoLocation

Retrieve bounding coordinates and distances with GeoLocation. You can also calculate and measure the distance between geopoints with this php class.

This is a PHP port of Java code that was originally published at http://JanMatuschek.de/LatitudeLongitudeBoundingCoordinates. A few modifications were made and an additional helper method to retrieve latitude and longitude from an address has been provided using Google's Geocoding API.

Examples

Get distance between two points:

	
		use AnthonyMartin\GeoLocation\GeoLocation as GeoLocation;
		
		// Set locations
		$edison_nj = GeoLocation::fromDegrees(40.5187154, -74.4120953);
		$brooklyn_ny = GeoLocation::fromDegrees(40.65, -73.95);

		echo "Distance from Edison, NJ to Brookyln, NY: " . 
			$edison_nj->distanceTo($brooklyn_ny, 'miles') . " miles \n";

		# Distance from Edison, NJ to Brookyln, NY: 25.888611494606 miles 


		echo "Distance from Edison, NJ to Brooklyn, NY: " . 
			$edison_nj->distanceTo($brooklyn_ny, 'kilometers') . " kilometers \n";

		# Distance from Edison, NJ to Brooklyn, NY: 41.663681581973 kilometers 

	

Get bounding coordinates

	
		use AnthonyMartin\GeoLocation\GeoLocation as GeoLocation;
		
		$edison = GeoLocation::fromDegrees(40.5187154, -74.4120953);
		$coordinates = $edison->boundingCoordinates(3, 'miles');

		echo "min latitude: " . $coordinates[0]->getLatitudeInDegrees() . " \n";
		echo "min longitude: " . $coordinates[0]->getLongitudeInDegrees() . " \n";

		echo "max latitude: " . $coordinates[1]->getLatitudeInDegrees() . " \n";
		echo "max longitude: " . $coordinates[1]->getLongitudeInDegrees() . " \n";

		/**
		*	Returns:
		*	min latitude: 40.47529593323 
		*	min longitude: -74.469211617725 
		*	max latitude: 40.56213486677 
		*	max longitude: -74.354978982275

Get latitude and longitude from address or location

	
	use AnthonyMartin\GeoLocation\GeoLocation as GeoLocation;
	
	$location = 'New York City';
	$response = GeoLocation::getGeocodeFromGoogle($location);
	$latitude = $response->results[0]->geometry->location->lat;
	$longitude = $response->results[0]->geometry->location->lng;
	echo $latitude . ', ' . $longitude;
	# 40.7143528, -74.0059731
