If that kind of 'accuracy' is good enough, just use a random number calculator.  'As the crow flies' it's around 500 km.

 

Unless you want to host an enormous database - and then you would only get the point-to-point distance not how far you actually travel - you could use a third-party service to provide the information.

 

http://www.google.com/search?q=distance+between+cities offers lots

Supposedly, this should do the trick. It isn't my code (I suck at math) and I haven't tested it, but give it a try.

 

$lat1 = 46.2341938036161; 
$lon1 = -63.124778021257015; 

$lat2 = 46.4141938036161; 
$lon2 = -63.118571124705284; 

$distance = (3958*3.1415926*sqrt(($lat2-$lat1)*($lat2-$lat1) + cos($lat2/57.29578)*cos($lat1/57.29578)*($lon2-$lon1)*($lon2-$lon1))/180);

 

Of course you still need a database with coordinates.

wow..ok you lost me what do i do with that.

It's a script that takes longitude and latitude of two locations and calculates the distance in KM. But you're right, if you don't know what to do with it, better use Google instead
