Question

Well i am working in a location based app and i need to find driving distance between two location on earth at the server end. i am coding the web service in php.

Till now i am able to calculate the aerial distance using the Haversine formula, but now i want to calculate the driving distance.

There can be possible duplicates for this question, but i was not able to find any help to calculate the “Driving distance” between two “coordinates” ie latitude and longitude instead of addresses in PHP

Answer 1

This should get you started…

$json = file_get_contents('http://maps.google.com/maps/nav?q=from:Buderim,Australia%20to:Brisbane,Australia');

$details = json_decode($json, TRUE);

var_dump($details['Directions']['Distance']['meters']);
